some days ago we changed our mail server. We were running a cyrus-imapd 2.1 on a Red Hat 7.2 box and now we installed a cyrus-imapd 2.2.10 on a Debian Sarge.
To do the migration I copyed all the users mailboxes and mail files (spool directory) and the mail "data" (lib directory) to the new box and, following the instructions from Cyrus page I converted the old seen files to skiplist. I did a reconstruct -rf user.* and all seemed to be running ok, also seen states.
The clients who are using this mail server are all MS Outlook XP. I know it doesn't have a good IMAP support, but our users wanted it. With some rules at clients we managed to store sent-mail on the IMAP server automatically, but after some hours of use, that rules failed. Trying to connect to the sent mailbox results on a System I/O Error on the client. The cyrus log, says more or less the same:
/var/log/syslogd:
imap[31053]: IOERROR: opening /data/mail/spool/cyrus/mail/user/ecolmenero/Elementos eliminados/cyrus.cache: No such file or directory
I looked for that file (cyrus.cache) and it exists. It doesn't happen to all users at the same time, I mean one user can have the error while other user is working ok. But when accessing a mailbox fails, almost all the user's mailboxes fail too.
I know hot to fix the error. If I reconstruct that user's mailboxes all works ok again, but the IOERROR appears again after some hours of works. I don't know how to reproduce it...
Anyone knows how to fix it? I installed the last cyrus-imapd version (2.2.12) but it didn't fix it. The error appears many times a day... Is it a cyrus-problem? Outlook??
Maybe useful data:
- Users have between 2000 to 6000 mails on the sent folder...
- /etc/imapd.conf

I hope anyone can help me. I don't know where to look and didn't find anything in google...
Sorry for my poor english.
Thanks to all in advance.
