Hello,

I'm running an Debian etch box with unstable and ever since the last upgrade to dovecot, I've seen odd things. At times, I would see emails would go missing from the Inbox or other folders, and I couldn't move emails that were moved from the Inbox to another folder back into the Inbox. These have seen gone away since I removed all dovecot.* files and .index* files from my Maildir's and let Dovecot regenerate them as needed.

The most current thing are these errors:

dovecot: Aug 30 11:38:33 Error: IMAP(blair): file mail-transaction-log-view.c: l ine 183 (mail_transaction_log_view_set): assertion failed: (max_file_offset == ( uoff_t)-1 || max_file_offset <= file->sync_offset)

dovecot: Aug 30 13:05:21 Info: imap-login: Login: ashley [127.0.0.1] dovecot: Aug 30 13:14:06 Error: IMAP(ashley): Corrupted index cache file /home/ashley/Maildir/dovecot.index.cache: record points outside file

Anything I can do to help here? I don't have a core file, even though I have 'mail_drop_priv_before_exec = yes'.

The other odd thing I noticed is after running /etc/init.d/dovecot stop, I would have several imap processes left over in my uid. They don't do much:

strace -p 5014

Process 5014 attached - interrupt to quit gettimeofday({1125460345, 997748}, {420, 0}) = 0 gettimeofday({1125460345, 998465}, NULL) = 0 poll([{fd=8, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=0, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 2, 410) = 0 gettimeofday({1125460346, 410768}, {420, 0}) = 0 gettimeofday({1125460346, 410890}, NULL) = 0 poll([{fd=8, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=0, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 2, 0) = 0 gettimeofday({1125460346, 411940}, {420, 0}) = 0 gettimeofday({1125460346, 412551}, NULL) = 0

However, lsof shows that the file descriptor 8 is a pipe back to fd 9 in the same process. Why would poll() be polling it's own file descriptor? Is this normal? Is this process waiting to do a fork later on and communicate with a child?

lsof -p 5014
