EdgeTransport.exe process appears to be leaking memory - high object handles

We are seeing an issue with an SBS 2011 whereby every week, pretty much to the hour, Exchange is unable to communicate with Active Directory.

We see event logs which suggest that Exchange is unable to find any global catalogs (there are 2) within the domain.

This has been researched extensively by ourselves and Microsoft - but we aren't really getting anywhere.

Earlier this week a discovery was made that, whereby restarting the EdgeTransport.exe service appeared to restore connectivity and solve the issues.


We've noticed that there were a few processes running with high object handles. One of which was uninstalled (Sage Gateway) and another disabled (A300_Service) but this made no difference. The next object with the highest handles is EdgeTransport.exe.

The server and exchange is fully service packed.

Any ideas or suggestions please?

What else is on the server?
Any Exchange integrated AV or Anti-Spam tools?

Other software potentially responsible includes:

Sophos (this has been disabled, issue still occurs)
Exclaimer Mail Disclaimers
C2C Mail Archiving

Anti-Spam is cloud based

Disabling the products isn't enough. That is like putting a blindfold over them. You have to actually remove the product and reboot to verify it is not the cause.

It is transport related, so Exclaimer or Sophos would be the places I would look.
In a lot of cases, simply removing the product, rebooting and then reinstalling the latest build resolves the issue.

In these kinds of cases I rarely look past third party software as the cause, and I usually don't have to.

Thanks Simon - going through those steps now. (The only problem is that it can take a week to really know if a remedial task has fixed the issue)
