Again me and again I am an old problem
It looks like last time (the past 2 times) is not rated seriously whole
situation,
And so, from my previous posts
(microsoft.public.exchange.admin, EdgeTransport.exe took 98% CPU time, Sent
5/15/2008)
(microsoft.public.exchange.admin, Exchange Server message size limits, Sent
5/19/2008)

One can conclude that the problem was in that the user was MaxSendSize:
unlimited and MaxReceiveSize: unlimited

What has been taken into account and all users rigidly exhibited both
setting 10Mb

And so all the same thing happen again!
User sent ~700Mb and HUB Transports die, as described in previous two posts.
But now user has MaxSendSize: 10Mb and MaxReceiveSize: 10Mb

What is the problem this time?
It seems that it is Exchange BUG.

Server Farm
2 Global Catalog Servers (Windows Server 2003 x86, SP2, Full Updated)
1 CAS/HUB Exchange Server 2007 SP1 UR2 (Windows 2003 x64, SP2, Full Updated)
1 HUB Exchange Server 2007 SP1 UR2 (Windows Server 2008 x64, SP1, Full
Update)
2 Mailbox Cluster Exchange Server 2007 SP1 UR2 (Windows Server 2003 x64,
SP2, Full Updated)

Also in Farm there 2 Exchange Server 2003 SP2, Windows Server 2003 x86,
SP2, Front and Back
97% all mailboxes are in Exchange Server 2007 farm.


Thanks,
Arman Obosyan.

Hello Arman,

Thank you for your post.

Please allow me to confirm that my understandings are correct. As I
understand it, the issue is:

You are experiencing a problem on Exchange 2007Server which is related
Message size for user and EdgeTransport.exe process crash issue. Previously
when the User limit MaxSendSize is the default value(Unlimited) and user
send 700MB mail, the HUB Transports will crash. However, now when you
adjust the User limit MaxSendSize to 10 MB, the issue still occurs.

If I have misunderstood your concerns please feel free to let me know.

Based on your description, it seems the MaxSendSize: 10Mb and
MaxReceiveSize: 10Mb didn't take effect to the User mailbox limit. Before
we go further, I would like to ask:

1. When will the HUB Transports will hang/crash? What operation have you
done that will cause it crash?
2. Are you using Exchange 2007 RTM or Exchange 2007 SP1?
3. What's the exact symptoms when the issue occurs?

As we can set limitation for sending message in 5 levels: Organizational,
Global, Connector, Server, User. I am not sure if the setting is you set is
a global message size limits. Please open Exchange Management console,
locate at organization properties for the Hub Transport. Click Global
Settings tab, open the properties of the Transport Settings. Please set the
transport limits you want.

For more information:

Managing Message Size Limits

http://technet.microsoft.com/en-us/library/bb124345(EXCHG.80).aspx

If you have configured them via Exchange Management Console, now you need
to check this specific user's settings using Exchange management shell.
Please open Exchange management shell and run the following cmdlet

Get-Mailbox -id "username" | fl

Check the maxsendsize attribute. You can modify it with the cmdlet below.

Get-Mailbox -id "username" -maxsendsize "the size you want"

For more information about how to use Exchange management shell to
management size limitation.

-administration/exchange-2007-message-size-limits.html

Please Note: Since the website is not hosted by Microsoft, the link may
change without notice. Microsoft does not guarantee the accuracy of this
information.

After performing the above steps, please check if the HUB Transports still
crashes or hangs?

If we cannot resolve the issue after we perform the above steps, please
help me collect some information for further investigation:

Information Need
==============
1. If possible, please capture some screenshot when the error messages
appear and send them to me : v-robmen(a)microsoft.com

2. Collect Exchange MPS report:

a. Enable Diagnostic Logging of Exchange Processes to Maximum level, to do
this, follow below article:

http://technet.microsoft.com/en-us/library/bb201668.aspx

b. Please download a tool from the following link:
http://download.microsoft.com/download/b/b/1/bb139fcb-4aac-4fe5-a579-30b0bd9
15706/MPSRPT_Exchange.EXE

c. Double-click the downloaded EXE file to collect the MPS report.
d. Please send the generated CAB file to me at: v-robmen(a)microsoft.com

By the way, have you tried running the Microsoft Exchange Server Best
Practices Analyzer Tool? If not, I strongly suggest you have a try to get a
overall diagnosis:

Exchange Best Practices Analyzer v2.8
http://technet.microsoft.com/en-us/exchange/bb288481.aspx


Hope this helps. Also, if you have any questions or concerns, please do not
hesitate to let me know.

Thank you for your time and cooperation

Yes, all true, all as you describe

1. When will the HUB Transports will hang/crash? What operation have you
done that will cause it crash?

At this moment we don't use any of monitoring software (currently waiting
Exchange Server 2007 Management pack for Operation Manager 2007, normal MP
full working)
We get a call from Help desk that internal messages are delivered slow, or
not delivered,
Checking HUB Server and get symptoms as I describe (increase in size
mail.que, ...)
By tracking logs shows that this happened after the user submits messages

2. Are you using Exchange 2007 RTM or Exchange 2007 SP1?
Currently all server in Exchange farm is Exchange Server 2007 SP1 Update
Rollup 2

3. What's the exact symptoms when the issue occurs?
The process EdgeTransport.exe took 98% CPU time, and
\TransportRoles\QueueDatabasePath\
file mail.que increases in the amount per minute at approximately 100mb,
then when the size mail.que reaches about 4 GB (sometimes at 2Gb) service
MSExchangeTransport.exe dies, after auto start its stuck at the stage of
starting. In same time I see that traffics comes from Mailbox server, whane
traffics stops I see how mail.que increases, if I stop EdgeTransport.exe and
delete all content in \TransportRoles\QueueDatabasePath\ and then start
EdgeTransport.exe all its repeats, only after I fount user who send large
mail (in Message Tracking) export all contet from his mailbox to pst and the
delete box all works fine.

EBPA runs regularly nothing special.


Collected screen shots and MPSReports already sent by mail

Thank you

Hi Arman,

Thank you for your clarification and additional information.

First, after checking the MPS report from the Exchange 2007 server, I
didn't find any Exchange services crash related errors in both Event log
and System information file.

Since this crash issue may be caused by several factors, according to my
research, let's try the following steps to continue:

Step 1: to set all messages limit to 10MB

a. Use the Set-TransportConfig cmdlet in the Exchange Management Shell or
the Hub Transport organization configuration properties in the Exchange
Management Console to set the MaxSendSize/MaxReceiveSize for all Exchange
2007 servers that exist in the organization.

Note: Organizational limits apply to all Exchange 2007 servers that exist
in the organization. The specified message limits apply to all Exchange
2007 servers that have the Hub Transport server role installed. On an Edge
Transport server, the specified limits apply to the specific server.

http://technet.microsoft.com/en-us/library/bb124151(EXCHG.80).aspx


b. Set Connector Limits

The following table shows the connector limits.
Source Parameter Version Default value
Set-ForeignConnector MaxMessageSize Exchange 2007 RTM and Exchange 2007
SP1 Unlimited
Set-ReceiveConnector MaxHeaderSize Exchange 2007 RTM and Exchange 2007
SP1 64 KB
Set-ReceiveConnector MaxMessageSize Exchange 2007 RTM and Exchange 2007
SP1 10 MB
Set-ReceiveConnector MaxRecipientsPerMessage Exchange 2007 RTM and
Exchange 2007 SP1 200
Set-SendConnector MaxMessageSize Exchange 2007 RTM and Exchange 2007 SP1
10 MB
Set-AdSiteLink MaxMessageSize Exchange 2007 SP1 Unlimited
Set-RoutingGroupConnector MaxMessageSize Exchange 2007 SP1 Unlimited


c. Use "Transport Rule" to set the "AttachmentSizeOver" for very Exchagne
2007 server. The default value in Exchange 2007 SP1 is "Not configured".



Step 2: check and disable SMTP rely on all Exchange 2007 servers.

Please temporarily disable all open rely on all Exchange 2007 servers to
drop the workload down.


Step 3. Disable Forefront program temporarily.

I found there are some Forefront services related errors in MPS reports.
Please disable Forefront program temporarily for narrow down purpose.
Moreover, why do you have a "QueueDatabasePath" under TransportRoles\
folder? The default path is TransportRoles\data\Queue\mail.que .


Now does your Exchange server/ EdgeTransport.exe still crash very often?


For more information about how to use Exchange management shell to
management size limitation.

http://www.msexchange.org/articles-tutorials/exchange-server-2007/management
-administration/exchange-2007-message-size-limits.html

Hope this helps.
