I have a system that is being used as a high performance NFS server

The NFS exported filesystem is on a Q-Logic FC card

isp0: [GIANT-LOCKED]
The disk is formated UFS2 and is big, but not *that* big yet
/dev/da1s1d 471860682 206516934 227594894 48% /usr/local/export
Every 12 hours or so the system crashes with a hard lock and no error messages in /var/log/messages or on the screen. I've moved all the disks to a duplicate system. If it continues to lock hard what's the possibility the issue is SMP?
See this message from yesterday (submitted to announce):
ftp://ftp.freebsd.org/pub/FreeBSD/ERRATA/notices/FreeBSD-EN-05:01.nfs.asc
In short, update your system.
Cheers, Erik
Since i am going to set up a SMP NFS server too, i would be interested if this really solves the OP's problem. After all, he is talking about a "hard lock with no messages..", as opposed to a "kernel panic", which in my understanding always produces messages.
