Answer/Solution: A connection was forcibly closed by
a peer. This normally results from a loss of the connection on the remote socket
due to a timeout or a reboot.
Right, its being dropped because it times out. The
server in question can initiate an SMTP connection, but if there's no route
back to the sever that initiated a connection to mine, it will time out. If the
packets can't find their way back, it breaks the connection. The problem is
routing - packets get routed to my server because my net block (destination
address) is routable, but the return traffic back to a "null routed" net block
(destination address) will time out. However you slice it, SMTP wont respond
when the server is attempting to communicate. I cant believe that I'm the
only one having this problem. Is there anyone else seeing multiple 10054's with
SMTP not timing out? Is anyone else using Sprint that has a mail server
receiving lots of SPAM that doesn't have a 10054 problem?
This
forum is cool!!

You won't see the 10054 error for not being able
to connect. this error means the connection was dropped by the other
end.

Timeouts and send error 10054
Yes I may try a different NIC. I have an integrated
3com NIC on a Dell Optiplex GX240. But the thing that points me away from
the nic is that I cant even ping the IP in question - right after the error
occurs, or even later, so the server is not there, its not just a problem
communicating. I ping the addresses in question from my workstation and not
the server, so its not just the mail servers nic that cant communicate
to the IP in question. It just seems to me that its the behavior of SMTP
when its trying to connect to a server that's not there. Another thing is
that I have never seen the 10054's at all if its a legitimate server. I
have also done searches through the log to see if any of the 10054 IP's
ever do get a good connection, and they don't. Another thing - Trace
routes on the IPs in question often show a net block from Japan,
France, brazil, etc. This is another thing that leads me to believe that
there isn't anything wrong with the nic. Maybe someone can answer this
question - If, under normal conditions, an Imail server tries to connect to
a server that's not there, what is it supposed to do, what should I see in
the logs?
Thanks again for the response
Mike,
You may want to check your patch cable(s), the
port(s) on your hub/switch/patch panel/router etc.. Also, it
could possibly be a flaky nic. You may want to try
a new card. Imail seems to like 3com 905's. FYI, quite a few people on
this list seem to have had problems with "server" class 3com nics on
Imail boxes.
Hope this helps!

Thanks for the reply Jamie,
I saw that KB article, but this is an NT4 box,
and there are no power or standby options. Is there anyone who had a
similar problem and found a resolution with NT?
|
Answer/Solution: Go to the NIC
properties and hit the Configure button. Then click the Power
Management button. Make sure that both, Allow this device to
bring the computer out of standby, and, Allow the computer to
turn off this device to save power, are NOT checked. |

I am
having a problem with my SMTP service going down and back up again
several times per day. Thankfully it only goes down for a few
seconds and then goes back up just fine, but sometimes it will go
down for a few minutes. This occurs when I get the following entry
in my SMTP log. We are an ISP that's been around a while, and we
receive approx 30,000 messages/smtp connections per day. I realize
that most of those connections are from spammers with hosed up
machines and DNS properties, but my log is riddled with entries
similar to this one: (IP and port have been replaced with x's
because they are random).
02-19-2003 20:37:00 SMTPD (0D6802C0)
[0.0.0.0] connect xxx.xxx.xxx.xxx port xxxx
02-19-2003 20:37:00 SMTPD
(0D6802C0) send error 10054
This
error will show several different IP addresses so there's no real
pattern to it. Some have shown up more that others and I have
entered several IP's that have caused this error in the SMTP blocked
IP list, but there are too many of them to truly keep up on it. I
know that this error is due to a connection initiated by a spammer
or some other type of mail server that just doesn't work. Reverse
lookups on the IP in question rarely come up with anything, and
usually the IP's in question cant even be pinged. I don't really
care that my logs are filled with errors like this, but the problem
is that whenever my SMTP service goes down and back up for a few
seconds, it is directly related to the time that the send error
10054 occurred.
Is
anyone else having this problem, and is there anything I cant do to
keep the SMTP service from going down when this
happens? This seems to be occurring more and more, and I am
getting more and more calls from customers that think the mail
server is down because they get a POP3 error whenever they try to
log in.
Thanks
in advance for any help with this one.
