java.lang.OutOfMemoryError: Perm Gen Space..again

Question

I followed the instructions from several great posts in dealing with this error when compiling my JSP and it seemed to go away ---for a while, but now it's back with a vengeance :( First off here are the 'specs':

• Spring 3.1.0 release
• Using WebLogic Server 10.3.5,

• Adjusted the STS.ini file to read as follows:

  -Dosgi.requiredJavaVersion=1.5
  -Xmn28m
  -Xms120m
  -Xmx2048m
  -Xss1m
  -XX:PermSize=256m
  -XX:MaxPermSize=512m
  

and here is the error I am receiving when trying to view my page:

The error went away a week ago after adjusting the default PermSize (don't remember what it was set to)...is there anything else I should be looking for here?

As a follow on to George D's answer: For weblogic, any changes to JVM args should be put in $DOMAIN_HOME/bin/setDomainEnv.sh (this is for Linux, should be a similar path for Windows).
