Customer is running Sun Identity Server 6.0SP1 with Webserver 6.0SP8
and J2SE 1.3.1_13 on Solaris 8 with latest patches.

During stress tests, the webserver restarts automatically as the
JDK crashes randomly with SEGV. During the tests, we run multiple java clients test driver instances(10) against Identity Server (does login/logout to IS).
