Root Cause:
This issue is seen with all version of WLS 10.3 and above when running with JDK1.6 with all fix packs.
java.lang.OutOfMemoryError:GC overhead limit exceeded -
Indicates that due to some reasons the garbage collection is taking an excesive amount of time.
Parallel collector will throw java.lang.OutOfMemory if much time is spent on GC. If more than 98% of time is spend in GC and less than 2% of hep is recovered an java.lang.OutOfMemoryError is thrown

Solution: (Workaround)
This java.lang.OutOfMemoryError:GC overhead limit exceeded can be avoided  by diadabling  the GC overhed feature in JDK 1.6 by using this argument to start scripts
-XX:-UseGCOverheadLimit.
