For the last several weeks I have had one server abend when backup starts.
Started about once a week, but has accellerated so that it abends with every

Backup has been upgraded to the latest build (9.1 build 1158.9). Server is
NW 6.5 SP5 (upgraded from SP3 when the problem began).

When loader is called, where is it loaded from? There is an old LOADER.EXE
in the nwserver folder, but the abend shows loader.nlm being used. Curious,
as it appears some abend logs posted show loader.exe.
Any assistance would be greatly appreciated.


Here is the abend file:
