[Xen-users] jre causes soft lockup

["Adam vonNieda" <adam.vonnieda@xxxxxxxxx>]

   Hi folks,

   As the subject says, I'm running a java process that consistently crashes my xenU domain. It's not an in-house written application, it's an oracle delivered utility, srvctl, which calls the jre. Below is some info. Let me know if there's other info I should be posting as well, this is my first post. Any insight would be appreciated.

   Thanks very much,
