Attached is a gcore and a pstack.

Customer issue: process stopped servicing requests.
1 thread is compiling, and 59 waiting for compiler.
Looks similar to 4800683.

Process is .kjs (wrapper around java) for ias6.5mu1, jdk 1.3.1_02-b02

Threads waiting on compiler (59 times):
  Monitor::wait
   CompileBroker::wait_for_completion
   CompileBroker::compile_method_base
   CompileBroker::compile_method
   Recompilation::methodOop_invocation_counter_overflow
   InterpreterRuntime::invocation_counter_overflow

A DESCRIPTION OF THE PROBLEM :
During the executino of our application, the java HotSpot Compiler goes into
an infinite loop trying to compile a method. After the application finishes,
CPU Utilization is very high due to the fact the compiler is in an infinite
loop.

There are many methods we are needing to exclude because of this or
hotspot core dumps. This is a very high performance application, and we
cannot afford to be excluding lots of methods. This particular method
is a backbone method for a part of our application (see workaround below).

Here is the pstack output for the offending thread:
