[Dovecot] [Fwd: dovecot-1.0_rc7 crashes (Login process died too early) with repeated deletes from thunderbird]
I've run this test on every permutation of poll and notify:
can NOT reproduce the crash:
--with-ioloop=select --with-notify=none
--with-ioloop=select --with-notify=dnotify
--with-ioloop=select --with-notify=inotify
--with-ioloop=poll --with-notify=none
--with-ioloop=poll --with-notify=dnotify
--with-ioloop=poll --with-notify=inotify
CAN reproduce the crash:
--with-ioloop=epoll --with-notify=none
--with-ioloop=epoll --with-notify=dnotify
--with-ioloop=epoll --with-notify=inotify
So it would seem that epoll is related some how.
As IDLE only seems to work well with epoll, I'm highly interested in
resolving this crash.
My Linux kernel is version 2.6.14.2
glibc 2.3.6
If any other info would help, please let me know.
If any other test combinations would be helpful, I will try to do them ASAP.
Regards,
Tim Schafer

From: Tim Schafer <tim_schafer at shipfsp.com>
To: Dovecot Mailing List <dovecot at dovecot.org>
I can consistently reproduce a crash in dovecot:
Select 20 or more messages and copy them to a test folder.
Go into that test folder and SHIFT-DEL the messages rapidly (holding down
SHIFT-DEL works best)
Just rapidly DELing them (even holding down DEL) doesn't do it (unless
it's the Trash folder)
I'm using the following namespace (in case that's relevant)
namespace private {
separator = .
prefix = INBOX.
inbox = yes
}
The /var/log/syslog for the session reads:
