Jetty IdleTimeout

Question

I am migrating from jetty7.6 to jetty-9.2. I am seeing that default value of idletimeout for jetty connections is reduced 10 times.

In jetty-7.6

<Set name="maxIdleTime">300000</Set>

In jetty-9.2:

<Set name="idleTimeout"><Property name="http.timeout" default="30000"/></Set>

Why So ?

And because of this I am continuously getting below exception :

WARN:oejs.HttpChannel:qtp607635164-14195: Commit failed
java.util.concurrent.TimeoutException: Idle timeout expired: 30000/30000 ms

Answer 1

put this in your ${jetty.base}/start.ini

jetty.http.idleTimeout=300000

that will restore your previous expectations.

It was changed from a default of 5 minutes to 30 seconds as a timeout simply because that's a better choice for the majority of websites.

I saw in jetty-http.xml : Set name="idleTimeout"><Property name="http.timeout" default="30000"/></Set> But when i tried to set java property "http.timeout" to 300000. It still shows me the same error with "30000(old value)". Why it is not set to the new value (why can't this be changed from java property) ? – Taurus

That is not a java System.setProperty, its a jetty-start / jetty-xml startup property. use start.jar --list-config capture the output, then edit your question to include this output. – Photosphere

FYI, this property is now jetty.http.timeout – Macaulay

@Macaulay I believe you mean jetty.http.idleTimeout since v9.3 – Clercq

Answer 2

Using Jetty 9.4 and HTTPS, the above solution doesn't work. To fix this I found an undocumented setting that doesn't appear in the .ini files:

jetty.ssl.idleTimeout=180000

Add that to your Jetty settings. start.d/<whatever>.ini or start.ini.

Answer 3

The correct setting is

## Connector idle timeout in milliseconds
# jetty.ssl.idleTimeout=30000

This can be found in ssl.mod file.
