Hi, I'm not sure if this is the right place to post but I'm running out of ideas on what to do, where to look or what to ask! :) I have been experiencing problems with my PHP and MySQL-based web application hanging when running a local Apache server on m$ Vista. I can't say for sure that the problem is Apache, but neither can I specifically narrow it down to MySQL or PHP. To be brief, the code runs perfectly on the following setups: Windows XP running Apache 2.2.4, MySQL 4.1, PHP 5.2.1 Windows XP running Apache 2.2.4, MySQL 4.1, PHP 5.2 Windows XP running Apache 2.2.4, MySQL 5.0.37, PHP 5.2.1 Windows XP running Apache 2.2.4, MySQL 5.0.22, PHP 5.2.1 Windows XP running Apache 2.0.59, MySQL 4.1, PHP 5.2.1 Windows XP running Apache 2.0.59, MySQL 5.0.22, PHP 5.2.1 Fedora Core 6 running Apache 2.2.4, MySQL 5.0.37, PHP 5.2.1 Three are no problems whatsoever on any of those setups, everything runs perfectly (as expected, the code doesn't try anything special!). However, on the following setups.. Windows Vista x64 running Apache 2.2.4, MySQL 5.0.37, PHP 5.2.1 Windows Vista x64 running Apache 2.2.4, MySQL 5.0.37, PHP 5.2 Windows Vista x64 running Apache 2.2.4, MySQL 5.0.22, PHP 5.2 Windows Vista x64 running Apache 2.0.59, MySQL 5.0.22, PHP 5.2.1 Windows Vista x64 running Apache 2.0.59, MySQL 5.0.22, PHP 5.2 Windows Vista x64 running Apache 2.0.59, MySQL 5.0.37, PHP 5.2 Windows Vista x64 running Apache 2.2.4 x64, MySQL 5.0.37 x64, PHP 5.2.1 x64 (from apachelounge.com) ..a few pages of a site using my web application can be browsed at most before "hangs" are experienced; the "Page Loading" animation just displays continuously. Opening another browser/tab allows the usage of a local version of PHPMyAdmin while the site which I attempted to access above still remains "hung", so there doesn't appear to be any problem which is bringing down Apache or MySQL altogether, each can continue to start and run other threads. However, the web application rarely functions again (i.e. clicking on other URLs for this local site doesn't bring any of the pages up) until either MySQL or Apache is restarted. This leads me to believe that something between Apache/PHP and MySQL is simply getting stuck at some point. Why this *never* happens on XP/Linux and continuously happens on Vista I just don't know, but the fact that this problem is 100% reliable in its occurrence (i.e. reproducible) means that something's up with either MySQL, PHP or Apache on Vista. I know that Apache won't even install properly on Windows Vista without disabling UAC etc (which obviously I've done or I couldn't have run all the test setups above ;) )... so I'm guessing that it is most likely to blame. Could this problem be some kind of restrictions within Vista on one process calling another (Apache with PHP calling MySQL)? Does Apache need to be fixed for Vista to comply with such a policy? I really don't know, I'm completely lost now and unfortunately my only current recourse is to move back to XP, which is hugely frustrating as I've *no other reason* to move back at all other than this not working. :( If anyone has any inkling towards what might be happening, or any information about incompatibilities between Apache and Vista, I'd really appreciate it if you could let me know. Thanks! :) All the best...
