Hi and thanks for your reply, However I mistakenly said I was running apache 2.2... Here below is my system info I have been running UniServer for months now and this problem keeps re-appearing, it lasts for a couple of days and goes back to working just fine!?! I see no correlation between any other program I may be running, computer load or whatever and the fact that it simply hangs... I would like to know if there is any way for me to trace why apache hangs this way? And meanwhile, is there some trick to killing the apache process once it hangs? My only recourse right now is to reboot my computer (even log off / log on doesn't work) PHP version = 5.1.1 apache2handler Webserver = Apache/2.0.55 (Win32) DAV/2 PHP/5.1.1 Database = mysqlt 5.0.17, lock.system=database Acceleration = full/604800, partial/604800 Operating system = Windows NT MARC 5.1 build 2600 Locale = en_US Thanks!
