Hi Frank,
Thanks for your quick reply.
If you crash in memset(), it's usually because you try to access unmapped >
memory - i.e. an invalid/NULL pointer.Do we need to handle this in our java
application? Usually while this happen, could it be due to the JRE we are using
may not compatible with the Solaris 10? The JRE we are using is (1.5.0_10-b03) for
solaris-sparc.
Difficult to say without more details. The JVM is attempting to create a
thread there and that fails, but whether that's a JVM/JRE bug, a bug in
your Java code (mis-calling some interface) or a Solaris libc-level or
even platform bug is impossible to say just from the stacktrace.
It could even be something as "mundane" as an environment setting -
ulimits come to mind, e.g. stacksize/VA size constraints, as the
application crash occurs trying to initialize the stack memory of a
newly-created thread.
