Thanks for 2.3.5 - it fixed a lot of stuff :) I see this Panic in my Director logs now, randomly and rarely:
Mar 07 11:01:29 pop3-login: Panic: file iostream-openssl.c: line 586 (openssl_iostream_handle_error): assertion failed: (errno != 0) Mar 07 11:01:29 auth: Warning: auth client 13625 disconnected with 19 pending requests: EOF Mar 07 11:01:29 pop3-login: Fatal: master: service(pop3-login): child 13625 killed with signal 6 (core not dumped - https://dovecot.org/bugreport.html#coredumps - set /proc/sys/fs/suid_dumpable to 2)
Hoping the above is enough to debug -- Tom
