Hi,
I was checking out the parallel deployment feature of tomcat 7 and
encountered an issue with PermGen space of JVM. After the initial
deployment (xyz##001.war), PermGen space reaches ~120mb of space and
after parallel deployment (xyz##002.war) it almost doubles (~205mb)
which make sense. Now if i remove the old war file (xyz##001.war) by
removing xyz##001.xml
($catalina_home/conf/Catalina/locahost/xyz##001.xml), PermGen space
doesn't come down. I have waited upto 4 hrs but no luck. Once i
restart the JVM then only it comes down to ~120 range. Is anybody else
faced this issue? I would hate to restart the JVM after deployment
which totally defeats the purpose of parallel deployment.
Setup details:
OS --> RHEL - 5.5 (64 Bit)
Tomcat --> 7.0.14
Java --> jre1.6.0_25 (64 bit)
Tomcat APR --> apr-1.4.5 (64 bit)
java service wrapper --> 3.5.9 (64 bit)
Attached are server.xml and wrapper.conf files.
Thanks in advance
Kapil
