--Apple-Mail-2-255508058 Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset=US-ASCII; delsp=yes; format=flowed Yesterday we upgraded an amd64 system from 6.1 to 6.2-PRE from a cvsup of September 20 evening. The overnight nightly dump to tape went off normally. This afternoon when the sysadmin was performing the level0 backup, the ffs_mksnap program locked up the entire system. It wasn't the expected short hiccup that mksnap sometimes causes -- it was started just prior to lunchtime and when we got back everyone had wedged login sessions and IMAP sessions, and ffs_mksnap was in "D" state according to ps and idle for about 90 minutes. The only way out was to reboot the system. I know this is very un-useful as a bug report, but I'm putting this out in case anyone else has noticed this. It has never happened to us before when we were running 5.4 and then 6.1 on this box. Nothing else changed on the system during this time. The disk in question is on an adaptec RAID controller with the aac driver. --Apple-Mail-2-255508058--
