We have a Sharepoint Farm with 3 web applications. 2 of them are working
properly without any problem. However the third application regularly causes an
error. In the event log :

Faulting application w3wp.exe, version 6.0.3790.3959, faulting module
msvcr80.dll,...

This error occurs 2 or 3 times a day, and terminates the w3 worker process. The
main difference between this webapp and the other 2 is that in this webapp we
use a workflows (not sharepoint workflows but WWF State machine workflows). We
couldn't find any clue about the cause of the problem. Do ypu have any idea on
how to overcome this issue?
