Hello,
we have an problem by re-deploying our jsf application war in tomcat 7.
Each time we re-deploy our application with tomcat7-maven-plugin we get an
permgen error.
Also undeploying and deploying with the Tomcat Web Application Manager doesn't
work and leads into the same error.
To get undeploying working we had to change the configuration in tomcats
context.xml to <Context antiJARLocking="true" antiResourceLocking="true">
otherwise the web-inf\lib directory is not removed.
I also used the find leaks function of Tomcat Web Application Manager after
undepolying, which shows that the webapplication is still in use,
after some time (30-60 seconds) executing find leaks again results in no leaks
found and the application deployment works again.
Also increasing the pergmgen memory of java vm helps to enabel re-deployment
some times more, but after to much re-deployments the out of memory exception
is back.
The Tomcat java opts used: JAVA_OPTS="-Xms2048m -Xmx2048m -XX:NewSize=1024m
-XX:MaxNewSize=1024m -XX:PermSize=1024m -XX:MaxPermSize=1024m"
Why is redeployment not possible? Is this issue known and can i do anything
about that?
Folowing exception occurs on second deployment:
