dovecot - Jun 2006 - Strange Error after some hour of inactivity.

Hi,
in near future planing migrate our E-mail server to new hardware.
Decided try dovecot as IMAP and POP3 server.
Compiled latest dovecot-1.0.beta8 version on Linux Fedora Core 3 machine (2.6
kernel).
Users database are on PostgreSQL server.
Everything working fine except some issues.

After some hour of inactivity (POP3 or IMAP) then connecting to check e-mail got
this error:
invalid I/O fd 8, callback 0x8064d30.
Next connection without service restart working fine again but only when in
dovecot.conf exsist this option:
login_process_per_connection = yes. When "login_process_per_connection =
no" , always got "invalid I/O fd 8, callback 0x8064d30" error.

from log file ( in dovecot.conf login_process_per_connection = yes):
...

also have troubles with maildir quota on POP3 module (IMAP works fine):

mail log:

Jun  1 20:29:44 srv1 dovecot: child 21465 (pop3) returned error 89
Jun  1 20:43:09 srv1 dovecot: Killed with signal 15
...

For this issue i found solution with manual compilation POP3 module:
appended dependence -o ../lib/mountpoint.o


Best regards,

error.
Could you do this and show me the result:

gdb /usr/local/libexec/dovecot/imap-login
x 0x8064d30

It should print the function name for that address.

Did you configure Dovecot with --ioloop=epoll? I think there have been
some problems with that, which might be related.

This doesn't look nice either. Could you get the gdb backtrace for it?
It should have written core file to /var/run/dovecot (or wherever your
base_dir is). If not, you probably need to do "ulimit -c unlimited"
before starting Dovecot.

Right. I've done that in CVS too.
