On SUSE linux running under VMWare
Reporter: Kathey Marsden
We made a change to enable the "Virtual Machine Interface " between the VM
server and the SUSE Linux client, to correct a time calculation issue in this
environment. Since then we have been seeing intermittent hangs, once in the
build during splitmessages and several times in the tests. The hang always
seems to be in some native code invoked from an internal java class.
This is lkely a VMWare bug, rather than Derby or JVM bug. Once that is verified
I will close this invald, but thought I would file it in case users encounter
the issue.
I will post a few sample javacore files. Here is one sample trace:
