Hello,

I had a problem today with a postfix process that I hope someone can
help with. Nothing critical, and probably not the fault of postfix
itself, but something I'd like to understand more.

On this particular machine I am running Postfix-20010228-pl03.

This afternoon I noticed some mail stuck in the active queue via mailq
i.e.

[rootrum alastair]# mailq
-Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient-------
AEF077D026* 3058 Tue Feb 26 12:07:02 richardnucoda.com
                                         xxxxxbbc.co.uk

(the xxxx is a real email address I see no reason to post)

I noticed this at 5pm.

Logs ;

Feb 26 12:07:02 rum postfix/smtpd[692]: connect from pernod[192.168.0.109]
Feb 26 12:07:02 rum postfix/smtpd[692]: AEF077D026: client=pernod[192.168.0.109]
Feb 26 12:07:02 rum postfix/cleanup[693]: AEF077D026: message-id=<LEEHIOIAIDFGAIHOKBGBCEAGCPAA.richardnucoda.com>
Feb 26 12:07:02 rum postfix/qmgr[30563]: AEF077D026: from=<richardnucoda.com>, size=3058, nrcpt=1 (queue active)
Feb 26 12:07:02 rum postfix/smtpd[692]: disconnect from pernod[192.168.0.109]

I could not get this mail to go with a 'postfix flush' (which is ok I
guess since 'flush' is for deferred retries I think).

Other mails, to the same domain have been sent without problem all
afternoon.

Trying to figure this out I looked at network connections (netstat) and
then, using 'ps' ;

[rootrum alastair]# ps -o pid,tt,user,cmd,tmout,flags,time,cputime,pri,wchan -p 695
PID TT USER CMD TMOUT F TIME TIME PRI WCHAN
695 ? postfix smtp -t unix -u - 100 00:00:00 00:00:00 39 tcp_recvmsg

This smtp process appeared 'stuck' waiting on 'tcp_recvmsg'.

Restarting postfix cleared this and the message went.

Why was it stuck? What might cause this? Would it ever have been
deferred or cleared?

Would a 'kill' on this process itself allowed delivery?

Any help in understanding this would be welcome.

Many Thanks,
