color=#0000ff size=2>Here's some more background on the IIS FastCGI
extension. Isapi_fcgi.dll does recycle the processes. Memory
leaks will accumulate for a while but resource consuming php-cgi.exe and
mapagent.exe processes should drop off after a while. The only catch is
that isapi_fcgi gives no control over how long the processes should stay
alive. For PHP, setting the following environment variables may help
roll the processes a little quicker:</FONT></SPAN></DIV>

is killed on Windows, the FastCGI ISAPI handler doesn't get
informed about it, and the first request fails. If you restart IIS

up.</FONT></SPAN></DIV>
