It's better to use the existing JMX Connector Server in 9.1. No need
to add -Dcom.sun.management to domain.xml.
Also, can you please try
1- kill -3 server-process-id
2- asadmin generate-jvm-report --type thread, --type summary and send
us the results?
Also, is it a VM crash? If yes, you should have gotten a crash dump (a file
named something like hs_err* in your domain's config folder or your home
folder).
Thanks,
Kedar
