V4R5 Apache -- "Internal Server Error"

I'm in the process of trying to certify some CGI programs, that currently
run on the old IBM HTTP server, to run on Apache.

The programs seem to run OK ... except every other request that is sent I
get a error 500 "Internal Server Error -- Cannot read script output pipe.".

If I refresh, or go back a screen, and resubmit the request the program
works fine.

Even if I just leave the same URL in the browser, and click refresh twice,
once I'll get the correct result, the next I'll get the 500 error.

The programs work fine in the original HTTP server.

Any suggestions on where to start looking?

Thanks!

david
