Hi.

FreeBSD 6.2-STABLE

Yesterday I typed
find /opt/disk1 -flags snapshot

it  started working and never finished. I tried Ctrl+C and Ctrl+Z, but
it  did  not work. I tried to type kill -9 <find pid>. It did not work
either.  It  seems  that da1 hung up. I tried to reboot server, but it
did not reboot and continued working.

After manually resetting the server, the disk works fine.

How do I prevent similar hang up in the future?
