Hi all. I recently upgraded from 1.0.0 to 1.0.7 version and found that process imap-login begins randomly crash:
pid 29997 (imap-login), uid 143: exited on signal 11 (core dumped) pid 32189 (imap-login), uid 143: exited on signal 11 (core dumped) pid 32121 (imap-login), uid 143: exited on signal 11 (core dumped) pid 31309 (imap-login), uid 143: exited on signal 11 (core dumped)
i guess that it happens during high load on CPU (but just guess) no anything upon upgrade changed - traffic, config are the same. can anyone help me? running FreeBSD 6.2, compiled from port with mysql, lda, kqueue, pop3 support.
