Fatal: master: service(imap): child 20258 killed with signal 6 (core not dumped - set service imap { drop_priv_before_exec=yes })
All, Just move our mail servers over to a new mail server running postfix 2.11.1 and dovecot 2.2.13 and getting the subject line errors in my /var/adm/files. People are complaining of loosing their connections to the mail server.
I've been able to google this error but haven't found fix for this yet. NOt sure where to put the drop-priv option in the config files either.
Any suggestions?

It looks like on the system that once we hit around 200 imap processes it stops there and no more imap processes can be created. Is there a number of max imap processes in the config file somewhere. By the way running on OmniOS:

Hi,
not shure if that helps.
In 10-master.conf file exists a "service imap { ... }" section. You could try to increase the "process_limit = " parameter in it.
On one of oour servers there we have "process_limit = 2048" and we habe about 1200 concurrent connections without problems.

That didn't work. Still seem to stop accepting new imap connections when we hit around 500 processes.

All I want is a chance to prove 'Money can't buy happiness'
Update: I had to fall back to the 1.2.17 dovecot code. Doing that solved the invalid user settings and dovecot inability to auto detect between mbox and Maildir format for user accounts and no longer have the limited number of imap processes either.
Not sure what I was missing in the config files, but this is the route I will stay on for now. If it helps here is the 1.2.17 config:

Doubble slash
After starting dovecot the following is run to take care of the fd limit:
/usr/bin/plimit -n 16384,16384 cat ../var/run/dovecot/master.pid
I was doing this same commend for 2.2. dovecot as well.
I do have ssl configured and working. My mail client confirms the secure connection is made.
Not sure why the dovecot -n showed double slash, it's not that way in the config file.

Find the first error/warning that Dovecot logs, which should happen just before you reach the limit.

Did you actually switch from sparc to x86 CPU in the server? If yes, then looks like the code to handle the switching could use some fixing.
But in any case you can just delete the .imap/ directories and have the indexes be rebuilt.

Yes,
I did switch from sparc server to x86. I also removed all the dovecot.indexes and .imap folders. I will try 2.2 again tomorrow with the process limits specified for imap, pop, and auth.
My concern is with auto detection of user accounts using mbox or Maildir formats. Is it still the case to support mix mbox and Maildir by commenting out the mail_location lines?

But in any case you can just delete the .imap/ directories and have the indexes be rebuilt.

Just a remark: this issue (Panic: file buffer.c: line 307 (buffer_set_used_size): assertion failed: (used_size <= buf->alloc)) was reported by me on 2014-01-11 on 2.2.10, it still occurs on 2.2.13. Indeed, we also switched from sparc server to x86. We also removed all the dovecot indexes. We use maildir only. However, the issue persists and I can observe this panic almost every day.
Thanks.
