Running the specweb2005_banking benchmark using a t2000 machine as a client,
the client machine's jvm repeatedly crashes 

The jvm is question is jdk1.5.0_06. Relinking to j2sdk1.4.2_10 runs the benchmark client load without issue. The following is the error dumped from the jvm:

#

The remainder of the file is attached to this bug.
This happened repeatedly for multiple executions of the benchmark client.
