I'm running Dovecot as proxy in front of some IMAP/POP3 Dovecot &
Courier-IMAP servers and in the last couple of days I've been seeing a
lot of imap-login crashes (signal 11) on both 2.2.18 and 2.2.25, all SSL
related. The following backtraces are taken running 2.2.25, built from
source on a test system similar to the live proxy servers.
OS: CentOS 6.8 64bit
Packages: openssl-1.0.1e-48.el6_8.3.x86_64, dovecot-2.2.25-2.el6.x86_64
built from source RPM.
Can post "doveconf -a" if required.
Core was generated by `dovecot/imap-login -D'.
Program terminated with signal 11, Segmentation fault.
