All,
I had a call from work this evening advising me all mail had stopped inbound and outbound out of my Exchange 2010 SP2 server. When I got onto the call we could see the queue had just jammed up around 3000 mails. When I looked at the logs I could correlate that there was no disk space issue, memory looked normal etc. But there was an event 15004 loogged which talks about back pressure and server resources.
What I realised was at the time the issue started, I had ran the following powershell script on my server..
D:\Logs\*.log | Export-ActiveSyncLog -Output:"C:\Temp\Logs"
I was trying to get a log for analysis of all mobile device users. So at the time I ran this script, it appeared to run fine, it generated all the correct logs and all was good. But now in hindsight, what appears to have happened is it caused an issue with my mail transport and all inbound/outbound mail stopped. I checked all exchange services and they were all started as I would expect. As soon as I rebooted the server all was good in the world again.
Am I just being really paranoid and this is a massive co-incidence that the server which has run flawlessly for almost 6 months died at the same time I ran this export script, almost to the exact minute? Has anybody seen any issue like this before?
Regards, John
