Happy holidays! I am experiencing an issue when trying to check my mail using IMAP. with Dovecot I have tried checking my mail using a full GUI client (Thunderbird) and telnet. Both times I get disconnected before all of my messages can be downloaded and I see an error in my mail log. Here are the details:
[root@cust19-1-prod-domain userqa]# dovecot --version 2.0.9
[root@cust19-1-prod-domain userqa]# dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-164.11.1.el5 x86_64 CentOS release 5.4 (Final) disable_plaintext_auth = no login_trusted_networks = 172.19.136.0 mail_location = maildir:~/Maildir mail_max_userip_connections = 100 mbox_write_locks = fcntl mmap_disable = yes passdb { args = scheme=plain username_format=%n /etc/dovecot/users driver = passwd-file } protocols = imap ssl = no userdb { args = username_format=%n /etc/dovecot/users driver = passwd-file } [root@cust19-1-prod-domain userqa]#
i try to check my mail:

I get some binary output and some mail headers, but then it crashes..
Not sure if you guys want to see all of the extremely verbose output, so I put it at the end of this message. The last messages that it processes is a message with an Excel spreadsheet attached to it (a .xlsx file)
i enabled core dumps:
echo 'DAEMON_COREFILE_LIMIT="unlimited"' >> /etc/sysconfig/dovecot
Now I see this in /var/log/maillog:
2012-12-25T17:53:47-08:00 cust19-1-prod-domain dovecot: master: Error: service(imap): child 11265 killed with signal 11 (core dumped)
core dumps are being written here, but they're empty:
[root@cust19-1-prod-domain userqa]# pwd /mnt/mail/userqa [root@cust19-1-prod-domain userqa]# ls -lh total 20K -rw------- 1 userqa userqa 0 Dec 25 17:52 core.11111 -rw------- 1 userqa userqa 0 Dec 25 17:53 core.11265 -rw------- 1 userqa userqa 0 Dec 25 17:58 core.11812 drwx------ 7 userqa userqa 4.0K Dec 25 17:58 Maildir [root@cust19-1-prod-domain userqa]#
What should I try now? Is it possible that Dovecot is having difficulty processing the attachment file? If I delete this user's mailbox file and send basic text e-mail to the user I can read/retrieve them just fine.. there only seems to be an issue when this message with its attachment arrives. The attachment seems small in size:
Content-Disposition: attachment; filename="report_amex.xlsx"; size=20527;
That means the attachment is 20527 bytes, correct?
Thank you for any suggestions/help you can offer!

Hi Eric,

Happy holidays! I am experiencing an issue when trying to check my mail using IMAP. with Dovecot I have tried checking my mail using a full GUI client (Thunderbird) and telnet. Both times I get disconnected before all of my messages can be downloaded and I see an error in my mail log. Here are the details:
[root@cust19-1-prod-domain userqa]# dovecot --version 2.0.9
There have been a lot of fixes since that version; can you confirm that this problem is not in 2.0.19 (or better yet, 2.1.12?)
i enabled core dumps:
echo 'DAEMON_COREFILE_LIMIT="unlimited"' >> /etc/sysconfig/dovecot
Does that work? The point is to set "ulimit -c unlimited". I don't know what package you're using, but Dovecot doesn't ship with an init script (at least, 2.0.9 didn't.) The only thing I know of is at http://wiki.dovecot.org/DovecotInit, and that doesn't use /etc/sysconfig at all.
Now I see this in /var/log/maillog:
2012-12-25T17:53:47-08:00 cust19-1-prod-domain dovecot: master: Error: service(imap): child 11265 killed with signal 11 (core dumped)
core dumps are being written here, but they're empty:
If you're still getting core dumps with 2.0.19, check your setting of "ulimit -c". It should be "unlimited" for this case. You may need to modify /etc/init.d/dovecot. My guess is that your /etc/sysconfig/dovecot modification is having no effect.
Jim
Isn't the version I have (2.0.9) newer than 2.0.19? The newest RPM I could find for CentOS was dovecot-2.0.9-2, not all that much newer than what I am using. I am not opposed to upgrading, just not sure if I am seeing much in the way of RPMs for my system that I can use to upgrade to a version that is much newer than what I already have.
I had taken the " echo 'DAEMON_COREFILE_LIMIT="unlimited"' >> /etc/sysconfig/dovecot" command from the Dovecot page on enabling core dumps for Red Hat (http://www.dovecot.org/bugreport.html). I have also added unlimited core dump files to /etc/security/limits.conf and verified that whenever myself or anyone else opens a shell that "ulimit -c" shows an output of "unlimited".
I don't see any mention of limits in my Dovecot init file either. The init script came with my RPM package and I have not modified it.
Even though I have unlimited core dump files allowed, I am still getting core files that are 0 bytes in size in the mail user's home directory. Any idea why?
[root@imapserver ~]# su - dovecot -bash-3.2$ ulimit -c unlimited -bash-3.2$ id uid=97(dovecot) gid=97(dovecot) groups=97(dovecot)

And then I get an empty core file:

2.0.19 is newer than 2.0.9. 2.1.12 is newer than that. You may have to take the spec file and rpmbuild your own RPM, if you want to stick with RPMs.

Check disk space on the filesystem where Dovecot is trying to dump? Is there some other reason it can't write there (but can create files) ?
