Problem fixed in version 7.3.1 patch 1 (build 6130)! (10-1-2012)

Question if others also see this problem:
(running 7.3.1 on OSX 10.6.Cool
500 users, 750Gbyte mail database, about 10.000 messages a day..

The process keeps some queue files as open, even if the queue is delivered well.
(we made already an official ticker out of it)

For example:

$lsof -c mailserve | grep queue

I see a lot off open queue files:
mailserve 84458 root 3r REG 14,5 3633 493267263 /mailserver/store/queue/00/4ee5bdb6-00000441.emf
mailserve 84458 root 68r REG 14,5 91758 493447165 /mailserver/store/queue/1a/4ee5fc0e-000014e4.emf

While the queue is already empty and delivered, they stay open (lsof):

$file /mailserver/store/queue/00/4ee5bdb6-00000441.emf
/mailserver/store/queue/00/4ee5bdb6-00000441.emf: cannot open `/mailserver/store/queue/00/4ee5bdb6-00000441.emf' (No such file or directory)
$file /mailserver/store/queue/1a/4ee5fc0e-000014e4.emf
/mailserver/store/queue/1a/4ee5fc0e-000014e4.emf: cannot open `/mailserver/store/queue/1a/4ee5fc0e-000014e4.emf' (No such file or directory)

grep 4ee5bdb6-00000441 mail.log

[12/Dec/2011 09:39:18] Recv: Queue-ID: 4ee5bdb6-00000441, Service: SMTP, From: <[/email]>, To: <fake<_at_>>, Size: 3409, Sender-Host:
[12/Dec/2011 09:39:18] Sent: Queue-ID: 4ee5bdb6-00000441, Recipient: <fake<_at_>>, Result: delivered, Status: 2.0.0

Every day, more and more queue files keep in use by the process ($lsof -c mailserve | grep queue | wc -l , for example about 480 per day )
, till there are too much open files (we got an socklib.cpp error) and we have to restart the process!
The strange thing is, about the 10.000 messages a day, only a random couple (about 500 a day) stays open by the process. In the meanwhile we restart the mail server every night, to clear them. (but that's not the normal way...)

I am curious about others, who can see the same thing. (before version 7.3, it never exists in our situation)

I can confirm this- we're also running Kerio 7.3.1 on OS X 10.6.
We have ~200 accounts- after four days of uptime, we had 264 queue files stuck open.
Restarting Kerio cleared them out, but the count is slowly rising again...

Maybe java (fulltext searching) makes something similar (KC 7.3.1 on OpenSuSE 12.1):

I've been monitoring this for a week now:


Bug or what?

We have the same problem here after the upgrade to 7.3.1, on Windows 2008 x86 server.

I have already made a support ticket for it.

Same problem... Server eventually locks up after 4-8 days, depending on traffic. Ticket open...apparently a bugfix is in the works.

Installed Patch 1 last night which seems to have cleared this problem for me. Good luck.
