the WAS started to load very slow and keep hanging for whatever actions selected, end with a “java.lang.OutOfMemoryError” error message in the WebSphere’s log file.
The default WebSphere’s Java Virtual Machine memory is not enough; you should adjust more memory to your WebSphere Application Server. See following guide to increase WebSphere’s JVM memory.
1. In WebSphere web console, select Servers -> Server Types -> WebSphere application servers -> Server Infrastructure -> Java and Process Management -> Process definition.
In Additional Properties section, select Java Virtual Machine
In General Properties section, put 256 for “Initial heap size” and 1024 for “Maximum heap size”.
Done, restart WebSphere.
