Version of UAT server he crash occured on:
SunOS sldn0096dap 5.8 Generic_108528-15 sun4u sparc SUNW,Ultra-Enterprise

We have run this test in several environments.

It consistently crashes in our UAT environment, but does not crash in our ENG (Engineering). We run it with a light load (5 users against a cluster of 2 servers), and both servers crash after about 8 to 12 minutes.

Both environments have the same level of WebSphere Software, and identical JVM versions, however the UAT (the one that crashes) environment has a later Solaris patch level. This tells me that it is not an IBM problem (would you agree ?). See the attached patches information. sldn0064dap is the UAT server that crashes, ln4d386cmp is the ENG server that does not crash.

I have also tried to eliminate some of the non-standard 3rd party libraries, like Wily Introscope and Profiler libraries. However the problem persists when I run it on UAT (See the latest error log file hs_err_pidXXX.log, the libraries left are now "standard" JVM libraries, albeit IBM ones).

The application uses encryption as well, so I turned the encryption part off, which means the IBM JCE libraries are not used, but this made no difference it still crashes.

Do you think the patch levels would be the problem ? I checked that the JVM's on UAT and ENG were identical (and they were).

Core available, but not show to much.

patch list attached.
