Actually, it hasn't. For the last few days we've been trying to pinpoint the problem by running half a dozen servers with different kernels and options. This 'kernel released in the 20th century' we have this problem with is the current stable kernel for debian. So instead of starting a distro war (and I thought canon/nikon, mac/pc were bad), lets be a bit more constructive. Plenty of people use the stable debian release.
Ahh OK, your previous message said it was resolved, did the traceback show anything?
It's happening on about half of our imap servers (20 or so), but on none of our other debian servers (hundreds). So it's not so weird to suspect a dovecot link. But it looks like it may be a driver issue on a specific range of hardware we use.
maybe install a slackware or gentoo box and add it into the farm and see if same problem exists there as well, if so, clearly dovecot, if not, clearly debian, its why I still keep a RHEL box handy, it sits attached to the "dev" unit until I need it to assist to prove/disprove something.
All the best.
