Hi Stack

JVM version is 1.6.  There was no profiling done. =20
In the TreeMap remove method we try to compare and then remove.  So may =
be
its not able to find the intended key as the map is corrupted and hence =
the
comparator is stuck and runs infinitely. =20

Regards
Ram

Is it for sure stuck there?  Maybe its stuck in comparator comparing?

What version of JVM?  Were you profiling at the time?
