Browser locking up with blank screen after viewing several graphics.

Issue

Browser locking up with blank screen after viewing several graphics.  Java console says java.lang.OutOfMemoryError: PermGen space.

Product Line

TAC I/A Series

Environment

IA Series Niagara G3

Cause

This can occur when viewing graphics screens from different ENC stations that have differing versions of modules. The browser will load the modules it needs from each ENC which can eventually use up all the available PermGen memory.

Resolution

Make certain all ENC stations are using the same version of the modules needed.
