I just got lots and lots of this: kern.ipc.maxpipekva exceeded; see tuning(7) However, tuning(7) on my system has no information about this tunable whatsoever. anglepoise:~ % uname -a FreeBSD anglepoise.lon.incunabulum.net 7.1-PRERELEASE FreeBSD 7.1-PRERELEASE #3: Tue Nov 4 15:40:44 GMT 2008 root@anglepoise.lon.incunabulum.net:/home/obj/usr/...

Anyone have any theories or experiences as to why for a certain user, some of his imap processes hang, and stay around for days and days? He just reported that his Thunderbird was timing out when trying to open folders, I looked on the server, and he had 3 old imap processes from 1 week+ ago. I killed those and his performance immediately improved. He checks mail with Thunderbird > 1.5

...d running RC2 on Thursday. I migrated an old Courier IMAP server, and the only issue I had was that I didn't understand how to enable quotas :) It's impressively fast, and I'm quite happy with it so far. This morning I found that dovecot had crashed, I had exceeded FreeBSD's kern.maxpipekva Has anyone successfully run dovecot under daemontools? I got it to fire up, but it didn't seem to work right.. I'm guessing it's a rights issue, but I haven't delved into it at all. Thanks! Rick
