Eclipse freezes in Windows 7

Question

Apparently after aplying some latest updates of Windows 7, Eclipse stopped working properly. It freezes very often for 30 second to 2 minutes. In fact the system also freezes, for example the music that is played in WMP stops, loading web pages stops, etc.

I tried it first with the newest Eclipse Kepler and thought it was only the new version but then fell back to Juno and the same thing happens.

My JRE is Java 7u45 but I also tested it with 7u7 and no changes.

It seems that in the time of freeze some I/O operations are taking place as the hard disk light flickers constantly.

It totally prevents from doing anything both in Eclipse as well as in the system itself.

Has anybody experienced such a problem lately? I have googled it up and all I found were some bug reports for Eclipse and 64-bit version of Windows.

EDIT: I tested it on a different machine with almost the same configuration and it works impeccably. Any idea how I can check on my machine, what causes the problem?

Still it happens only when I run Eclipse I have no other problem with any other application.

EDIT: I ran the Eclipse with -consolelog and here is the stack trace of exception thrown during the freeze.

I do not understand the downvotes on this question. Could you please be more specific? – Brushwood

Jagger, You might want to try this question on superuser.com as SO is specifically for programming oriented questions. This would explain the lack of interest and downvotes you've received. Best of luck to you. – Inappetence

@WilliamTate I do not agree. I do not think there are more users of Eclipse on superuser.com, that could help me, than the actual Eclipse users on stackoverflow.com – Brushwood

To moderators, this has nothing to do with superuser": this is a "**software tools commonly used by programmers", 100% in the StackOverflow FAQ: stackoverflow.com/faq – Brushwood

No way I could give you an answer, I'd try running a disk scan, and if the problem persists uninstalling the Eclipse Code Recommenders plugin. – Oestradiol

@GOTO0 The code assist is the reason I use Eclipse in the first place. :] – Brushwood

The error seems to be in some Google code which is not part of core Eclipse. What do you have installed in Eclipse? – Density

@Density I do not have anything more installed apart from the standard delivery contained in the file eclipse-java-kepler-SR1-win32.zip. – Brushwood

Are you sure the windows 7 updates caused the problem? Have you tried doing a system restore to back before the updates were applied and verified that it works? – Sarita

@Trever As much as I loved to do that I do not have such a possibility. I am not sure whether it update caused it or not. The Eclipse was working fine on my machine. I also checked the behaviour on a similar machine (the same hardware and software) as it is my company one and on the other machine everything works perfectly. It looks like the Eclipse tries to access a file on my drive and this I/O operation blocks almost all resources of the machine. – Brushwood

@Brushwood I had the same problem here (I could not identify the error in stack it is in german) and after lots of tests I found out that the problem was the google update process that runs in background. After I disabled it the eclipse worked like a charm. I also made a test restarting the google update process again and the problem came back. So see if you have such process give it a try. Let me know. – Gustave

@JorgeCampos: The error message could be translated more less like that to English: "The request could not be executed due to a device I/O error". The device in that case is my hard drive, I assume. Which file is being accessed I have no idea. Second of all, yes I did have the GoogleUpdate.exe process but shutting it down regrettably has not solved the problem. Anyway, your answer is a type of answers I am looking for. – Brushwood

@Brushwood Until I found out what was wrong I was disabling every unnecessary proecss on the machine until the google process. Sorry that was not your case. But, still, you can do the same. Also, as the error states I/O error you should see what is your hard drive manufacturer and download a especific test tool. Every brand has its own. As I've worked in a assembler industries programing some tests and drivers, sometimes there is nothing wrong with the software is just the hardware. Befor you format your pc, you should consider testing your HD. Hope it helps – Gustave

Answer 1

That German message could indicate serious issues. Encountered similar issues with multiple machines recently.

The checklist was like this:

• Make sure, that files are backed up
• Before further investigation, a quick hard disk health test
  • Check the health diagnostic (SMART) data of your hard drive, using a tool like HD Tune
    • If there are errors, especially the ones related to SSD wear level or pending/replaced sectors, your hard drive is basically saying goodbye
• The file system may be corrupted
  • Check & fix the file system (if required at boot time)
  • Independent of checkdisk results, one could use FSC to verify system files
• Check eclipse configuration
  • Reduce available concurrency and resource allocation settings of indexer plugins in Eclipse to a minimum
  • Disable indexing plugins
  • Test with an out of the box eclipse installation
  • One may delete local maven repositories and other temporary or intermediate storage locations
• Check for IO overload.
  • Have a look at the disk view in the resource monitor (accessible via taskmanager) for identifying IO intensive processes
    • Do you have many files checked out and running something like Tortoise Shell-Extensions?
      • Try to work in Eclipse without the Windows Shell & Explorer: Kill all explorer.exe instances via the task manager (CTRL+Shift-ESC). One can run 'explorer' again from within the task manager, if needed.
        • If no problems occur, remove or reconfigure such shell extensions, reboot and continue as normal (here, I got one problem solved)
  • Disable on access anti virus protection temporarily, perhaps after a full scan
  • Stop and/or Uninstall other IO intensive background processes
• There could be driver problems
  • Try updating or downgrading to a recently replaced storage driver (or the driver shipped with Windows, if possible)
• Boot and test in safe mode (press F8 before Windows splash screen on startup)
  • If you can work without problems here, the problem is most likely caused by services or other software components, something that has been disabled in safe mode (one would need to do further investigation regarding problematic software)
• Check for data transfer errors or other hardware failures
  • Check (pull & plug) the cables
  • Test the disk at other connectors (or better other controllers) or in another computer
  • Copy your working directories onto another physical drive (perhaps an external disk) and see, if you can work there without errors
  • 'offline' memory testing using a tool like: memtest86+

That is a lot of hints. I will go with starting the Windows in safe mode, let us see, what happens. – Brushwood

Nope, the same thing happens in safe mode. – Brushwood

Answer 2

Windows some times have problems with updates, you can try to use the Restore System tool. In most of the times this solve that kind of problems.

See the documentation here http://windows.microsoft.com/en-us/windows7/products/features/system-restore;

Answer 3

In my experience, Eclipse hangs the computer because it is rebuilding some internal search indexes or databases. Slowing down frequently after an Eclipse Software Update or a change to a major version.

I was unable to understand exactly what happens inside eclipse, I think that software update or version change could affect negatively to workspace metadata.

So I found great relief removing the .metadata inside the workspace and reimporting all the projects.

Remember:

• just to be sure don't lose anything, backup your workspace directory before delete .metadata
• close Eclipse before remove .metadata directory

Reimport all projects it is quite easy. All you need to do is select from menu File -> Import -> Existing Projects into Workspace.

I have a Mac, but under Windows should be the same. Then select the root directory of your workspace and import all projects.

This issue happens with a brand new installation of Eclipse, so the projects are not the problem here. Also as I wrote copying the same version of Eclipse to another quite similar machine proved that there is something wrong with my machine. – Brushwood

Answer 4

As others have suggested, the issue appears to be coming from the Code Recommenders plugin. It may not be a permanent solution, but I would try uninstalling that plugin temporarily and seeing if the problem persists.

Outside of that, I would just try the general PC troubleshooting steps:

1. Restart the computer
2. Reinstall the JDK
3. Reinstall Win 7 and Eclipse (nuclear option)

Guggenheim

I read some other threads on Stackoverflow. Problem persists even after deactivating those plugins. – Brushwood

It's a shot in the dark, but, is this machine running off of a HDD or a SSD? Any problems with other CPU/drive access intensive applications? Since you mention that it works flawlessly on other machines, I'm thinking it may be a hardware or low-level OS issue with this particular computer. – Guggenheim

Answer 5

This issue seems related with Eclipse Code Recommenders. They have just released a new version of this plugin today, check update notes. Maybe you could try to unsinstall or update that module before your IDE gets freezed.

Did you try to use other eclipse installers/versions? I would suggest you to try it with Spring STS IDE, it's just another eclipse with some customizations.
