Issue:

WASP is running out of memory when executing reports, or other administrative actions in UMP

In the wasp.log, the following error message was found:

 

ERROR [http-bio-443-exec-7230, org.apache.catalina.core.ContainerBase.[wasp-engine].[localhost].[/].[jsp]] java.lang.OutOfMemoryError: PermGen space 

Cause:

Max perm size memory assigned in wasp was low for the type of tasks the user was executing in UMP.

Resolution:

The solution was to change the initial parameters on the wasp java server by modifying the following:


max_perm_size = -XX:MaxPermSize=512m


to


max_perm_size = -XX:MaxPermSize=1024m

 

STEPS:

1. Open wasp in RAW config:

Press CTRL key, whilst right clicking the wasp probe + Select “Raw Configure…”

2. Navigate to “startup” > “opt”

3. Edit the “max_perm_size” value, click OK, and Apply.

4. Restart the robot that is hosting the wasp probe.
