Hi,
Wondered if anybody could share some wisdom. I have a Delphi/asp application running under IIS 6 on a win server 2003 box. Unfortunately the worker process serving the application pool is terminating multiple times a day with no real explanation in the logs or event viewer other than numerous exceptions within the ntdll.dll.

The application pool has a single worker process, rapid fail protection is switched on (5 in 5) and pinging is disabled.

What else should I be looking at to improve the stability of the worker process? Would increasing the worker process to two improve matters providing there was sufficient resource? Also what decent debug options are there out there?

Cheers.
 
What identity does the application pool run under? If you want to rule out permissions increase the rights of the account it's using, I tend to find fiddling with this sorts them out.
