[Dovecot] Reproduced the Login process died too early issue.
Hi.
I tried for some time to reproduce the "Login process died too early
issue".
It seems related to when the system run out of file descriptors, to
force the issue i forwarded 3k of messages trough the server(using
thunderbird).
I also tried with my usual mail application - mail.app, but no luck
there.

Aug 26 18:46:36 soekris postfix/cleanup[14739]: fatal: accept connection: Too many open files in system That would be a system limits issue, not a dovecot issue iirc. Youi'll need to raise the limits for fds (file descriptors) in your system for the dovecot user to be higher than it currently is (not really sure what you should raise it to).
There may be another way (for instance _maybe_ there's a dovecot option for the config), I'm not sure though.

Yup, but only the spawned children ought to go down, not the main daemon

So something leaks file descriptors. Could you check which Dovecot process is leaking them? Assuming Linux, look at /proc/*/fd/ directories where * being pids of dovecot, imap-login and imap processes. I'd guess one of the imap processes has lots of fds to some file?
Does this look normal, or a sign of a file descriptor leak?
This is for the PID of dovecot root 8683 0.0 0.0 1780 648 ? Ss 12:04 0:00 /usr/sbin/dovecot
