Troubleshooting: Problems with JVM and out of memory errors

On Solaris, a runtime process fails and you receive an out of memory error.

java.lang.OutOfMemoryError: PermGen space

Solution

You need to set the value of MaxPermSize variable to 384M or larger

  1. Starting and stopping quick reference.
  2. Open the WebSphere Integrated Solutions Console.
  3. Click Servers > Application servers > server1 > Process definition > Java virtual machine.
  4. Set the value of MaxPermSize to 384M or larger. For example, enter the following generic JVM arguments: XX:MaxPermSize=384m.
  5. Click OK, and save the changes.
