Hi there We have a pair of servers running FreeBSD 9.1-RC3 that act as transparent layer 7 loadbalancer (relayd) and pop/imap proxy (dovecot). Only one of them is active at a given time, it's a failover setup. From time to time the active one gets in a state in which the 'thread taskq' thread uses up 100% of one cpu on its own, like here: ---- PID USERNAME PRI NICE SIZE

Running the nightly from two days ago. The Dovecot log shows no errors, but I keep getting login errors for a few users. top shows: 71486 user1 1 96 0 4552K 2408K lockd 0 0:00 0.00% imap 11170 user2 1 96 0 4440K 2480K lockd 0 0:00 0.00% imap And a ps aux shows that these processes have been open for hours.

Hi, all-- I've got a 1997 Dell XPS D300 which has been rock-solid over the years, which I'd just upgraded via a PowerLeap iP3/T-1400C. The system seemed stable for several days, so I cvsup'ed and updated this machine from 4.7p10 to 4.8-STABLE, only to get a panic a few hours later. Can anyone make an educated guess as to whether the panic below is related to this upgrade, or

Hi all, Sorry for bothering you in this dev mailing list, I'm using libguestfs to customize some vm using as bases the ubuntu cloud images.
