2014-07-14 Thread Maciej Uhlig 
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.

CJ Keist - 2014-07-15 06:22:
 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?

 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.

Re: Fatal: master: service(imap): child 20258 killed with signal 6 (core not dumped - set service imap { drop_priv_before_exec=yes })

2014-07-10 Thread CJ Keist 
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.


Best,
Urban

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

well, how much folders do the have

keep in mind that fpr IDLE you have one connection per user and
folder
10 users with 10 folders behind the same NAT router are 100

2014-07-10 Thread CJ Keist 

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.
