I've been happily using XAMPP 1.7.4 on Windows XP for many weeks then today I suddenly have a problem. On startup, apache generates the error message "(OS 10022)An invalid argument was supplied. : Child 3388: Encountered too many errors accepting client connections. Possible causes: dynamic address renewal, or incompatible VPN or firewall software. Try using the Win32DisableAcceptEx directive."
This message is logged repeatedly (i.e. several zillion times) - causing the computer to run out of resources and lock up.
I've tried the Win32DisableAcceptEx tweak: this stops the error message appearing but the apache server still does not repond to page requests.
I suspect this problem may have appeared as a result of a recent Windows update - e.g. KB2544893 or the latest cumulative security update for IE8 - and I wonder if anyone else has had similar issues.
I'm also using Kaspersky AV 11.
