Thanks. See the "sanitized" doveconf -n output below. Unfortunately I can't post log entries. Looking at the various data I'm collecting, the crashes are always occurring during busy periods, when the maximum numbers of connections configured on the backend IMAP servers is reached. As a side note, all the backend servers are running using valid SSL certificates. Perhaps under load, or when the per IP connections limit is reached, one of them is disconnecting unexpectedly, or doesn't send the certificate?

It seems to error on ssl certificate not received.
Can you post doveconf -n and logs?
doveconf -a is usually not wanted.

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.
