Microsoft Exchange Transport service stops by itself - 18.Jun.2008 9:28:25 AM

We run Windows Server 2003 R2 SP2 and Exchange Server 2007 SP1 with the Update Rollup 2 installed. Every now and then our Hub Transport server stops working with no warnings - the Microsoft Exchange Transport service just stops by itself, and no events explaining why the service has stopped are logged to Event Viewer.
 
Digging the Event Viewer I found the following:
 
     Event Type: Warning
     Event Source: MSExchangeMailSubmission
     Event Category: MSExchangeMailSubmission
     Event ID: 1009
     Date:  18/06/2008
     Time:  07:18:07
     User:  N/A
     Computer: <server-name>
     Description:
     The Microsoft Exchange Mail Submission Service is currently unable to
     contact any Hub Transport servers in the local Active Directory site. The
     servers may be too busy to accept new connections at this time.
 
Even though Service Control Manager is configured to restart the service if it crashes, nothing happens – we solve the issue simply starting the service manually.
 
This has also happened to our Edge Transport server.
 
I have searched Microsoft Support, Exchange Blogs (MS-official and no official), the internet, but I couldn't find anything. Does anyone have any idea of what's happening? Is there any way to correct this and/or automate the process of restarting the service (like monitoring the event id 1009 from MSExchangeMailSubmission, since it’s the only one being logged, with “pure” Windows/Exchange – that is, no 3rd party tool/application installed to do the monitoring)?
 
Thanks!

Status: offline 		If your exchange server runs out of resources it will stop the transport services...this way no more e-mail come in.

It is called Back Pressure.

Have a look at http://www.msexchange.org/articles_tutorials/exchange-server-2007/management-administration/understanding-back-pressure-feature-exchange-server-2007.html

Status: offline 		Thank you rishishah, but back pressure occurs when you run out of disk space on the disk where the queue is located, and it does not stop the Microsoft Exchange Transport service: it just makes the service stop accepting new messages until the queue is cleaned and disk space is reclaimed - we have plenty of disk space where the queue is located.

What happens here is that the Microsoft Exchange Transport service just stops, as if someone went to Service Manager and stopped it there - no warnings, no errors, no nothing that could give me a clue of what's happening.

Status: offline 		till you find event logs that relat to you issue, i sugets you sue the net start command and schedule it every few mins to run and start you rlevant services.

Atleast this way they will start back up.

I know this is not want you are looking for, but try and dig around for logs or events.

Well, in RTM (at least) it seem to do. Have a look at this blog post containing your Event ID: http://mostlyexchange.blogspot.com/2006/11/exchange-2007-back-pressure-and-smtp.html

Searching the Internet also gave one hit on error on SID on the Exchange server but that really seems far fetched.

Status: offline 		I have the same setup and i'm having the exact same error and can't find any traces for my problem, this same behavior is happening with other Exchange Services, but mainly with Transport Service.

Did anybody find a solution?

Thanks

We ended up migrating to a new server (for other unrelated reasons) on July 16th, since then the problem hasn't occurred again.
