Exchange 2007 send queue


Exchange 2007, Exchange Server, Exchange server administration

Here's a puzzle for you. I have found no helpful information on this anywhere.
We have 2 exchange 2007 CCR clusters and on both clusters the number of emails stuck in the send queue builds until I fail the clusters over. I am finding this is necessary about every two weeks now.
The exchange servers are patched to the latest SP1 and rollups. They are on windows server 2003 SP2 with the latest patches as well.
We use spotlight on Exchange which shows me the send queue on the information stores, but it agrees with the number of emails in performance monitor on each exchange server so I know this is accurate.
Noone is complaining that their emails are not being sent however, which I find odd, and when I fail the servers over this queue clears immediately.
Any ideas as to why this is happening and how to stop this behavior?

Have you check your DNS logs? Are there any other symptoms on this machine? Is their a redundant nic on the machine? Could that be the issue. I would need some more network information but I would be more than happy to continue troubleshooting with you if you update this post.

This is really a weird one, did you try and contact Microsoft for this?

I have not contacted MS yet on this one, no. It’s not a critical thing at this point, more of an annoyance. Was hoping someone else had encountered this and knew how to fix it.

Have you tried sending an email to yourself to verify that they go through? Is it only from an individual user that gets stuck? Anything in the error logs that might point us some where? I had an issue a few months back where the server would stop sending and receiving every 2 days because the database was full. I would not have figured that out except for the error logs it created.

Inbound and outbound emails appear to be flowing just fine. When I look at the queue veiwer there are no building or stuck queues, I only see this when I look at performance monitor counter MSexchangeIS Mailbox - messages queued for submission.
This number is building daily although as I have already said noone is complaining about mail they have not received or was not received on the other end.
Once again, failing the ccr cluster over clears this up, but no emails show as stuck in any of the queues when I look at the queue viewer and there are no errors inthe event log.
Spotlight on Exchange and SCOM both show this number and will also break it down as to how many in each mail store, but you cannot find these emails anywhere on the exchange server unless you look at this counter in perfmon.

I see no other symptoms, no. This happens on both mail servers which are both CCR clusters. The only reason I even found out failing the servers over cleared this up is because one post I found somewhere said they found this to be true for them and they had the same issue. There is not a redundant nic, no, just the additional nic for the heartbeat of the CCR cluster. What DNS logs do you mean and where do I find them? Do you mean the logs on the DNS servers? What am I looking for there? We have several DNS servers.
