Hello,
we have a Cyrus 2.5.11 on Debian 7 using murder (2 frontends, 3
backends, 1 mupdate, about 5000 mailboxes) in production environment,
hosted by a VMware cluster 6.5.
Suddenly, ALL mailboxes have becomed inaccessible.
In the log, we found many messages like this:
master[5965]: process type:SERVICE name:imaps
path:/usr/cyrus/bin/proxyd age:82.255s pid:5987 signaled to death by
signal 11 (Segmentation fault)
I tried many times to restart the cyrus service on all servers without
success.
Users are authenticated correctly, error occurs when they try to access
the mailbox (trying with a manual connection using telnet, client dies
on a "SELECT INBOX" command after a successfull login)
This is the output of one core dump:
Core was generated by `proxyd -s'.
Program terminated with signal 11, Segmentation fault.
