And i see the process limit and stuff warnings, just reporting because I seem to remember Timo saying any error is considered a bug, so just in case...

Going to double my process limit from 100 to 256 and bump up the vsz_limit and see if I can make it go away

Hmm. Maybe it's opening a new auth connection for each user? I'll check it out later.

2010-08-26 16:20:51 auth: Error: net_accept() failed: Too many open files

This should be solved somehow. I guess Dovecot doesn't warn that your file limit is lower than the client_count (default=4096). Run ulimit -n 8192 or something before starting Dovecot. I'll add a check for that.

2010-08-26 16:20:51 master: Warning: service(auth): process_limit reached, client connections are being dropped

This can be expected.

2010-08-26 16:21:21 auth: Panic: file auth-request-handler.c: line 85 (auth_request_handler_unref): assertion failed: (hash_table_count(handler->requests) == 0)

Half a minute later. I guess the process was idle-killing itself.

I guess this has to do with the crash and restart of auth process. I'll see if I can reproduce and maybe avoid these somehow.
