Rule Execution Server and dead classloaders in permgen space of JVM

Troubleshooting


Problem

Running the jmap -permstat command against a process running Rule Execution Server shows many dead classloaders such as: 0x00000007abec4820 0 0 0x000000078baeac60 dead ilog/rules/util/IlrBinaryClassLoader@0x00000007736dde50 0x00000007ab8fb678 2 273192 0x00000007ab8fb6c8 dead ilog/jit/jvm/IlxJITClassLoader@0x0000000773956328 How can we reduce the amount of permgen space required by these classloaders?
