[mapguide-users] Preserve Session Data to Restore after Service Restarts?

[nclayton]

I received this Application Error when the service crashed:

Event Type:	Error
Event Source:	Application Error
Event Category:	(100)
Event ID:	1000
Date:		4/9/2008
Time:		2:24:55 PM

ntdll.dll, version 5.2.3790.3959, fault address 0x0002c853.

and these were recorded in Error.log for MapGuide:
