Exception after 5-6 deployments to weblogicServer cluster with the help of Jenkins, build tool used is Ant. Restarting the ManagedServer and Adminconsole temporarily fixes the issue.

Possible duplicate : java8 "java.lang.OutOfMemoryError: Metaspace"

What could be the issue ?

Answer 1

Gotcha !

Admin console is currently holding 2 ManagedServers, both ManagedServers having low MaxMetaspaceSize, updated the value from 512 MB to 1024 MB.

 XX:MaxMetaspaceSize=1024m

Issue is fixed !
