Towards the end of June 2012, we started to see many reports in various forums, LinkedIn Groups, and twitter, about the Forefront TMG Services stopping unexpectedly. These issues had the corresponding events in the Application Event Log:

Source: Service Control Manager Event ID: 7034 Level: Error Description: The Microsoft Forefront TMG Firewall service terminated unexpectedly. It has done this

And\Or

Source: Microsoft Forefront TMG Firewall Event ID: 14057 Description: The Firewall service stopped because an application filter module C:\Program Files\Microsoft Forefront Threat Management Gateway\w3filter.dll generated an exception code C0000005 in address when function CompleteAsyncIO was called. To resolve this error, remove recently installed application filters and restart the service.

These issues were primarily seen when using TMG's Web Publishing feature to publish an SSL site.

On June 29th, the Forefront TMG Team announced that Rollup 2 fixes the issue. See the original announcement here: TMG Services Stopping Unexpectedly
