A Debian server with an existing (and perfectly) running cyrus imapd run out of disk space. After deleting some unused old stuff, there is enough space again. But for one single specific user it is no longer possible to connect via imaps:
Apr 10 20:55:21 myhost cyrus/master: about to exec /usr/lib/cyrus/bin/imapd Apr 10 20:55:21 myhost cyrus/imaps: executed Apr 10 20:55:21 myhost cyrus/imaps: accepted connection Apr 10 20:55:37 myhost cyrus/imaps: mystore: starting txn 2147483675 Apr 10 20:55:37 myhost cyrus/imaps: mystore: committing txn 2147483675 Apr 10 20:55:37 myhost cyrus/imaps: starttls: TLSv1 with cipher AES128-SHA (128/128 bits new) no authentication Apr 10 20:55:45 myhost cyrus/imaps: login: [<local ip number>] <myuser> PLAIN+TLS User logged in Apr 10 20:55:46 myhost cyrus/master: process 1775 exited, signaled to death by 7 Apr 10 20:55:46 myhost cyrus/master: service imaps pid 1775 in BUSY state: terminated abnormally
I've tried to run
cyrreconstruct -r user.<userid>, tried to reboot the box, all without success. It's definitely not a client side issue, tried with thunderbird and mutt - both fail.
The strange thing is, every other user could use the imap server without any problem, it just fails for this specific user.
Any hints how to make the user's imap access working again.
I've enabled protocol level logging for the questionable user, it shows that imapd process dies after receiving an imap
SELECT "INBOX" command.
