Following dialogue with MS tech support, it's starting to look like these problems may be being caused by issues with running IIS5/ASP.NET on Windows 2000 Advanced Server. Some configuration changes have been put into effect today that may help reduce the number of errors we're seeing.

However, we will be running more tests and monitoring the servers over the course of next week to try and establish if this is the case. If found to be, we will then start looking at reconfiguring the servers with Standard Server rather than the Advanced edition.

Regards

Actually this is not the case atall. When we develop software we guarantee it. We guarantee that, should the customer identify a problem we will start investigations into the problem within a specified time (normally 8 working hours). If the problem cannot be fixed quickly, then work-arounds will be discussed and proposed where possible. Problems (under our contracts) include operational problems (when the systems are run on supported platforms) that are not due to software bugs and also include missing or faulty functionality. It appears that Archant are giving their software suppliers a “very easy time” (we would love customers like yourselves).

I1, Fair comment!

The problem we've got at the moment is identifying the exact cause of these errors. We cannot reproduce them on any other platform than the production webserver environment. Even when running on a development server, with a load simulator giving a greater load than the production environment (and on less powerful hardware) - the system runs perfectly.

This is where we're concentrating our efforts at the moment as the production servers are running Windows 2K Advanced Server, as opposed to the 2K Standard Server in the development environment. There have been a few reported issues which seem to implicate 2K Advd server, with similar problems to these.

If a few days of memory usage & allocation logging indicates that all's OK from the physical memory perspective, then the issues must be down to the differences between 2K Standard and 2K Advanced. If this is the case, we'll try rebuilding the servers as 2K Standard....

I'll post an update once we've reached some conclusions.
