If you're going to 1.4.3, check with Symantec on this first.

Otherwise, if you want to go 1.4.2, make sure you get any other EEBs that go along with it. There is a RAID controller patch that is pretty important and I can't remember if it's in 1.4.2 or not.

I had seen exactly that behavior from a pair of 5000s we put in back
in February. One of them got a RAID controller replaced, there were a
couple of EEB-type patches applied, all of which seemed to help, but
the frequency of the hangs wasn't often enough to really say there was
a statistically-significant improvement.

We did end up at 1.4.2, and have not had a problem since, and it's
been long enough now that I consider the issue resolved.
