This is on a Windows 2008 server running Exchange 2007 HTS and CAS.  This problem happens about twice a week where we get the following 2 errors, then about 5-6 hours later SMTP becomes unresponsive and we need to manually restart the Microsoft Transport Service.

What else is on the box? Dr Watson errors on Exchange are very unusual. I haven't seen one with Exchange 2007 before. Given it is pointing to transport, I would be suspecting AV, Antivirus, Disclaimer tools etc.

There is a listserver software (from Ikakura) called Active Subscriber, but I disabled it for a week and I still got the errors/stoppage.

If it interacts with Exchange in any shape or form then disabling it is not enough, because its hooks will still be in the system. You need to remove the product.
The problem may not be with the actual product doing what it does, but the way that it has hooked in to Exchange which has caused instability.
