[storm-user] storm crashed with sigsegv?

Hi Guys,

I built a small storm cluster in our colo, it includes 1 nimbus, 1 zk, and
3 workers. They are fine for about one month, and today I saw that the
cluster was down. I log in the machines, and I found that daemontools(the
supervise process) is busy restarting the workers. However, the workers
process starts and exits immediately. I had to kill the daemontools, and
restart daemontools made everything back to normal.

I got a bunch of error files hs_err_pid*****.log, with top of the content
as follows:

An unexpected error has been detected by Java Runtime Environment:

Did anyone see this before? I searched but didn't see any related.

Thanks for any input.
