I would call in some hardware experts.  You may have
a disk drive that is failing (stopped responding to
request) and I/Os are queueing up and therefore the whole
system stops responding.

Have you tried taking a memory dump when this happens?

Do you have anyone who can look at this dump?
I don't recall if you said if you have HP support or not.

Good Luck,

Barry
