[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.

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.

Daniel

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?

[Dovecot] Reproduced the Login process died too early issue.

Does this look normal, or a sign of a file descriptor leak?

This is for the PID of dovecot
