This problem occurs on 4.1.2 and 4.2.1 (maybe earlier versions, too) running on the CGI version for Win2k.

This may be related to bug 16313.

Randomly when I have a page redirect using the "location" header command, I get the message:

"CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are:"

I can then refresh the browser and see the page (usually).   It happens one time every 5 - 10 pages viewed.

No event log entry is made, and no other information is provided.    

Here's the interesting bit:
1.   It doesn't happen all the time
2.   It doesn't happen at all on another Win2k machine of mine (same software config)

The major difference between the two servers is the speed of the second server.   The failing server is a dual processor server, while my happy server is a single processor PIII.

I have looked further into it, and found that it is related to the mssql and odbc drivers - it doesn't fail if I use mysql. 

Bug #9852 discusses this in more depth, and I feel that it is what I have, so I've posted some further comments to it.

The issue appears to be timing related.

Same problem as #9852.
