Hi, I'm seeing the following in my logs. Twice so far, no idea what caused it. I do however have the core dump if that is of any use. > Jan 4 11:14:11 karif dovecot[20876]: imap(username): Panic: file imap-client.c: line 841 (client_check_command_hangs): assertion failed: (!have_wait_unfinished || unfinished_count > 0) > Jan 4 11:14:11 karif dovecot[20876]: imap(username): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0xa64ea) [0x7f6f99fa64ea] -> /usr/lib/dovecot/libdovecot.so.0(+0xa7a18) [0x7f6f99fa7a18] -> /usr/lib/doveco...

Hi Jake, thanks for fixing this. I have installed now the newly built package on my production system and will report, if any more core dumps occur.

Hello Timo, from the maintainer of the OpenCSW package I got the below answer. As the newly build package yields another different commit hash (which I cannot find on GitHub too), I would ask, if you are sure that the commit hash-output in 'doveconf -n' is generated correctly? The headline of 'doveconf -n' with the newly build package is # 2.2.25 (68082dc):
