Description jchristi 2005-10-02 08:17:17 UTC 
One thread is running ProfilerRuntimeCPU.copyLocalBuffer, the other is in
ProfilerInterface$1.handleEventBufferDump

Found one Java-level deadlock:
=============================
"RSMScheduler_Worker-14":
  waiting to lock monitor 0x00b8b97c (object 0x035a0000, a [B),
  which is held by "RSMScheduler_Worker-5"
"RSMScheduler_Worker-5":
  waiting to lock monitor 0x00b8badc (object 0x036cd190, a java.lang.Object),
  which is held by "RSMScheduler_Worker-14"
