Solution

The key error in the stack trace is the java.lang.OutOfMemoryError exception. The initial max heap size is 512 megabytes, but if the application is very large, and it needs to use more than the default 512 megabyte heap size, this error occurs. Increase the max heap size:

  1. Start the test server.

  2. Log on to the Administration Console.

  3. Select Servers > Server Types > WebSphere application servers > server1 > Java and Process Management > Process definition > Java Virtual Machine

  4. Change the value of the Maximum heap size field. For example, change the value from 512 to 1024.

  5. Save the changes, then restart the test server.

  6. Republish the application.
