FATAL ERROR in native method: JDWP No transports initialized error while starting hybris server in debug mode

Question

While trying to start my hybrisserver in debug mode I got the following error messages and hybrisserver stopped. I tried but not able to solve. Any help please.

FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197)<br/>

There were 5 failed launches in a row, each lasting less than 300 seconds.
Giving up.
There may be a configuration problem: please check the logs.

Answer 1

@thijsraets is correct. Either you have to check where is the port (8000) has been occupied or you can override the default value to something else in local.properties file.

tomcat.debugjavaoptions=-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=y,address=8001,suspend=n

Run "ant all". This will configure debug for port 8001.

OR

You can change the JVM parameters in wrapper-debug.conf file...

wrapper.java.additional.23=-Xrunjdwp:transport=dt_socket,server=y,address=8001,suspend=n

Answer 2

People who encounter this problem seem to already have something else bound to the debug port, try changing the port in: tomcat.debugjavaoptions

Answer 3

The same thing happened to me and tried to kill the server and restarted it safely. I followed these steps:

1. ps aux | grep java . this will help me to find the PID , Process ID
2. kill -9 PID

If you want to kill all the tomcat processes you can do

pkill -9 -f tomcat

this will restart the server safely.

A process kill -9 doesn't restart the server safely – Busiek
