Thread: Courier IMAP issues after Precise upgrade

-

after upgrading 11.10 12.04 seems though courier imap having issues.
once log in seems though connection dropped.
see output below showing can connect, can interact server can't login.

sy@twistie [505] log >nc localhost 143
* ok [capability imap4rev1 uidplus children namespace thread=orderedsubject thread=references sort quota idle acl acl2=union starttls] courier-imap ready. copyright 1998-2011 double precision, inc. see copying distribution information.
1 login my@email.com wrongpassword
1 no login failed.
1 login my@email.com correctpassword
sy@twistie [505] log >

i've upped debug level courier , here's output of login attempt mail.debug log.

may 1 19:54:31 twistie imapd: connection, ip=[::ffff:127.0.0.1]
may 1 19:54:33 twistie authdaemond: received auth request, service=imap, authtype=login

may 1 19:54:33 twistie authdaemond: password matches successfully
may 1 19:54:33 twistie authdaemond: authmysql: sysusername=<null>, sysuserid=5000, sysgroupid=5000, homedir=/home/vmail, address=my@email.com, fullname=<null>, maildir=email.com/my/, quota=0, options=<null>
may 1 19:54:33 twistie authdaemond: authenticated: sysusername=<null>, sysuserid=5000, sysgroupid=5000, homedir=/home/vmail, address=my@email.com, fullname=<null>, maildir=email.com/my/, quota=0, options=<null>

looks me though gets authenticated nothing happens , connection drops.

weird bit work few hours start getting problem. restarting courier processes doesn't fix reboot of system until fails again after few hours.

there's nothing obvious in logs , has worked past 5 years or so.
i'm stumped next. have idea on issue be?

i'm glad i'm not person suffering this! upgraded dev machine ran fine several hours pushed same updates production machine.

~24 hours later i'm having exact issue on both machines.


[edit]
rebooting server work. ubuntu getting windows down pretty good. -_-

on topic have debugging turned on can. i'll see tells me if goes down again tomorrow.
