500 internal server error bug

in the current version (4.0.6?) there is a slightly annoying bug (which might actually be two) when you run the Apache server (1.3.20) for a little while, PHP eventually stops working (it "falls asleep" -- the PHP ms-dos window just stays in the tray doing nothing and has to be force quit), and all requests to the site for a PHP file return a 500 "internal server" error, like "blah.php" -- "blah.html" or any other non-PHP files are downloaded perfectly. this also happens when you cause a 404 with a php file, example: http://www.roogroup.com/this_file_does_not_exist_and_never_will.php <-- returns a 500 (instead of 404), even when PHP isn't "asleep" also, both leave only this in the error log: [Wed Oct 17 18:00:41 2001] [error] [client 1.2.3.4] couldn't spawn child process: c:/php/php.exe the only way around this that I've found is restarting Apache and closing any locked up instances of PHP. I won't do that for now, so that you can all see at my server: http://www.roogroup.com/ I was told this had been fixed in a new version, but I can't seem to find this version anywhere. if anyone knows if this is my fault, and how to fix it, PLEASE let me know, otherwise, I hope the folks at php.net can fix this in the next win32 release. my info: AMD K6\2 450mhz w/ 128 MB ram Windows ME (4.90.3000) Apache 1.3.20 PHP Win32 4.0.6 MySQL (newest... forget the version) <-- note about MySQL: I had the bug before I installed MySQL, so I don't think this is causing it. regards, -andrew saturn
