We have recently migrated about 250 sites from a Win2K server to a new
Win2k3 Web server along with several dozen sites from an older Win2k3
install. The new box is dual Xeon processor, 2GB RAM. From performance
monitoring, it looks like the CPU is mostly loafing and the memory use is
40 - 55%. All sites were set up with their own anonymous user , app pool
user identity and corresponding app pool. The UseSharedWPDesktop registry
key is set to 1. As far as activity level, the sites are a mix of
lucky-to-get-one-visitor-a-day to fairly busy. They are a mix of static
HTML, ASP and a smaller portion ASP.NET with possibly a few PHP scripts.

We started seeing issues with COM+ errors showing up in the server
Application log. This seems to be impacting the ASP sites. They get a 500
"Server Too Busy" error. I can not find a particular pattern to the COM+
error nor the sites being impacted. The specific pages having errors often
are ones which are using ASP to only include header and footer HTML. I've
used log parser on the W3svc logs looking for a misbehaving site which might
be doing a buffer overrun or equivalent or some other common denominator
preceding these, but do not see any suspects.

Below is a sample of the errors from the Application log.

Can someone offer guidance on how to troubleshoot the source of these
errors? And also offer some ideas about what sort of thing causes such
errors?

Thanks.
