Hi All, I have had a couple of situations today where sync_master has terminated abnormally, and I am trying to figure out where to look for the problem. I am running Cyrus-IMAPd 2.3.3 under CentOS 3.6. The first of the log entries for the two terminations show: <snip> master[6348]: process 22661 exited, signaled to death by 6 </snip> Which according to 'man 7 signal' says that a signal 6 is a SIGABRT. Any ideas what would have caused this? The second error is curious too. <snip> syncserver[23808]: IOERROR: creating quota file /rep1/imap-backup/var/lib/imap/quota/c/user.changed.NEW: Too many open files syncserver[23808]: DBERROR: error storing user.changed: cyrusdb error master[6348]: process 23808 exited, signaled to death by 11 </snip> The odd thing about the second "Two many open files" error is that a cat of /proc/sys/fs/file-nr shows: 2175 520 235928 Which suggests that 2175 is the maximum number of open files the machine's had, which is miles away from the file max of 235928? Anyone have some ideas about what might be going on here?
