I don't have a test case developed yet, and the corefile was truncated. This
is consistently reproducible, so I can try to put one together if needed.

The nature of the problem is I have 100 threads working concurrently to
simulate a dataflow pipeline. The output of one thread is fed into the
following thread. I'm processing 500,000,000 floating point numbers. About
1/2 way through, the core dump occurs. This did not occur with the 1.2.2 VM.


Here is how I ran the test.

java version "1.3"


I'm not sure what problem with the JRE1.3 that I ran my application in my system
I got the message below sometimes.

# HotSpot Virtual Machine Error, Unexpected Signal 11

By the way, what I have in my application has one thread runable that calls
native jni methods, 3 other threads in pure java. All threads have the normal
priority (5). When I run it, it's crashed (not everytime). So what's problem?
