Director with dovecot 2.3 and Panic/Fatal error

Hi,

after the upgrade to Dovecot 2.3 for our director ring we found some times in the log errors like this:

Mar 18 14:22:51 Panic: imap-login: file iostream-openssl.c: line 599 (openssl_iostream_handle_error): assertion failed: (errno != 0) Mar 18 14:22:51 Fatal: imap-login: master: service(imap-login): child 1726 killed with signal 6 (core dumps disabled - https://dovecot.org/bugreport.html#coredumps)

Backend is still Dovecot 2.2.36 and Director is 2.3.10. I hope it can be fixed.

Thanks
