AndreBR -> Microsoft Exchange Transport service stops by itself (18.Jun.2008 9:28:25 AM)
Hello to all! 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!

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

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.

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.

What antivirus and backup software are you using...? try disabling both one by one to check if any of them is interfering with the Exchange Service...

AndreBR -> RE: Microsoft Exchange Transport service stops by itself (8.Jul.2008 6:45:52 AM)
There's no antivirus software installed on the Exchange box; we are using Tivoli Data Protection but it doesn't appear to be the cause of the problem, since it happens way after the backup has finished. Anyway, thank you for your suggestion!

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.

AndreBR -> RE: Microsoft Exchange Transport service stops by itself (8.Jul.2008 7:07:15 AM)
Thank you, Jesper, but our server has Service Pack 1 installed and plenty of available disk space on the volume where the queues are located.

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

AndreBR -> RE: Microsoft Exchange Transport service stops by itself (6.Aug.2008 10:03:42 AM)
I've never found a solution. We ended up migrating to a new server (for other unrelated reasons) on July 16th, since then the problem hasn't occurred again.
