Hi,
I was wondering what platform you're on, Windows 2003, windows200,XP OR NT?
P45858 suggest upgrading to 9.1D09 if your OS in NT4 or windows2000.
what Service pack level are you on? ($DLC\version).
Same applies for the other windows platforms if you use XMl/SAX when the error happens.
Other error which is fixes in SP09:
20040128-018 Controls SmartWindow with Microsoft Web
Browser. OCX control causes a prowin32.exe
ACCESS_VIOLATION error.
Does the error happens randomly or with a specific program?
If with a specific program could there be an ocx involved or memptr or XML handling then maybe it helps to upgrade to SP09.
Like Lee said 4GL trace is a very good way to determine where the error takes place.
I suppose that in the db log you have a 794 error at the time the error occurs?
Regards,
Casper
