When fockopen is used on a non working IP address (e.g. to test if some server is currently running) it seems to cause resource leaking. Even if fclose is used properly, and the php page has finished. This behaviour does not occur with working IP addresses.

This can be verified with windows task manager by looking in the handles column of apache.exe.

When repeated many times (>10000) Windows XP will collapse because applications will no longer be able to open IP ports.

I am using the windows binary on with Apache/1.3.24.
