Description Need Real Name 2002-11-12 23:57:15 EST 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 Galeon/1.2.6 (X11; Linux i686; U;) Gecko/20020830

Description of problem:
I am running squirrelmail-1.2.8-1 with imap-2001a-15 and xinetd-2.3.7-2.
Periodically, imapd stops successfully responding to connection requests, and
requires xinetd to be restarted. After restarting xinetd, imapd will respond
properly for a while...but will eventually wedge again.

Version-Release number of selected component (if applicable):
imap-2001a-15

How reproducible:
Sometimes

Steps to Reproduce:
1.Set SquirrelMail to use imap:

    IMAP Server          : localhost
    IMAP Port            : 143

2.Enable imap using ntsysv and restart xinetd.

3.Let it run for a day or so, and watch it eventually fail.
	

Actual Results:  When wedged, /var/log/maillog gets this:

Nov 12 20:22:38 gateway imapd[9936]: imap service init from 127.0.0.1
Nov 12 20:23:00 gateway imapd[9937]: imap service init from 127.0.0.1

Expected Results:  When operating normally, /var/log/maillog records:

Nov 12 20:26:19 gateway imapd[9971]: imap service init from 127.0.0.1
Nov 12 20:26:19 gateway imapd[9971]: Login user=vsmith
host=gateway.codegnome.org [127.0.0.1]
Nov 12 20:26:19 gateway imapd[9971]: Logout user=vsmith
host=gateway.codegnome.org [127.0.0.1]

Additional info:

Enabling the -cc flag for xinetd creates the following errors in
/var/log/messages. This error appears immediately, not just when imap gets wedged.

Nov 11 19:16:21 gateway xinetd[15551]: descriptor 3 set in socket mask but there
is no service for it
Nov 11 19:16:21 gateway xinetd[15551]: Consistency check detected 1 errors

Same here on my production server----
Are there any workarounds?
Comment 2 Alan Cox 2002-11-16 20:13:12 EST 
Seen similar too - go back to the older xinetd seems to cure it
Reassigned to xinetd
Comment 3 Gary Benson 2002-11-18 05:34:54 EST 
I've been having problems with my mailserver recently, although not identical to
the above.  When using mutt it would occasionally hang for a couple of minutes;
I presume that during that time the connection would time out and be recreated.
 I've had nothing untoward in /var/log/{messages,maillog}.

Anyway, I just downgraded to xinetd-2.3.4-0.8 and I'll let you know if the
problems continue.
Comment 4 Gary Benson 2002-11-18 12:22:22 EST 
FYI my problems went away after downgrading to xinetd-2.3.4-0.8.
Comment 5 Mike A. Harris 2002-11-18 13:12:37 EST 
Reassigning bug to xinetd package maintainer.
