We could, if you reported the jdk version you are using. A SEG_FAULT
indicates a bug in the java virtual machine. The Hotspot machines have
shown several of those. In multiprocessor machines, there is a
workaround for some of these. Another possibility is to upgrade to a
final release. 1.3.0_02 seems to work fine.
Other reason for having SEG_FAULTS is when the JVM gets out of memory,
since not all of the native code mallocs,... are checked. So, you can
also try to increase process memory limits for the JVM.
The fact that it happens only with "big" wars, like jetspeed, has little
to no relation with the problem, only that you are stressing more the
JVM, both memory and threading. Jetspeed is pure java, so any
segmentation fault is a jdk/jre problem.
