[Dovecot] out of memory on dovecot alpha5
Hello
Once a day i have these errors in doveecot.log:
dovecot: Dec 16 14:06:04 Error: auth-worker(default): .Out of memory (Needed 52 bytes) dovecot: Dec 16 14:06:04 Error: auth-worker(default): sql(login,<ip>): Password query failed: MySQL client ran out of memory dovecot: Dec 16 14:06:06 Info: imap-login: Disconnected: user=<login>, method=PLAIN, rip=<ip>, lip=<ip2> dovecot: Dec 16 14:06:06 Error: auth-worker(default): pool_system_malloc(): Out of memory dovecot: Dec 16 14:06:06 Error: child 23022 (auth-worker) returned error 83 (Out of memory)
And after that nobody can login
I do /etc/init.d/dovecot restart and then it's working for a day
Before upgrade to alpha5 i was used 0.99.x series without eny errros on this server
What can i do to debug this?

You probably need to bump the shell limit on per-process memory; search man sh(1) for 'ulimit'.

You probably need to bump the shell limit on per-process memory; search man sh(1) for 'ulimit'. i've checked ulimit -a output:
core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited

it seems there is no limits for memory

Maybe increase this setting:
auth_process_size = 256
Although I would have thought 256MB is enough. Maybe it's leaking memory..
And after that nobody can login
It should be restarted automatically, and that works with me. If you kill all "dovecot-auth -w" processes and try to log in, do logins work anymore?
