ID: 32002 Comment by: jonohlsson at hotmail dot com Reported By: tlamay at cte1 dot com Status: Open Bug Type: Apache2 related Operating System: Windows 2003 PHP Version: 4CVS-2005-02-17 New Comment:
must say i have this exact problem myself running win 2k / apache 1.3.33 / php 4.3.10 / Zend optimizer 2.5.7 and phpBB forum the apache log is filled with those erealloc errors and the browser page goes blank with a "server not found" message ...but i think it only happens if browsing with IE. mozilla works fine. weird isn't it? i've also tried changing php.ini memory settings, but this deosn't affect the apache log at all Previous Comments: ------------------------------------------------------------------------ [2005-02-17 20:46:17] tlamay at cte1 dot com Okay, after a bit of tweaking I got the latest PHP5 running. It crashes within 8-10 minutes. I have since migrated back to 4.3.10, the most stable version for me at the moment. Funny thing about the PHP5...when it crashes, Apache doesn't ever restart. The server stays completely down. I have to physically start it again. This behavior doesnt occur in 4.3.x.

Apache restarts every 5-10-15 minutes now versus every 30-45m with PHP 4.3.10.

Below is a snippet from Apache 2.0.52 error log. This restarting problem does not occur with 4.3.6 and 4.3.7. I have not fully tested 4.3.8. The restarts occur at regular intervals, and the least frequently with 4.3.10 (averaging every 30-45m). The Apache child thread restarts causing all web clients to disconnect (I guess this issue is particularly bad on Windows since there's only one child?) This can cause my ecommerce customers to loose POST data or mess up their orders in other ways, and at least cause time out issues on pages. I would love to know how to backtrace on Windows but I cant seem to find instructions. PHP error log isnt showing me anything relevant to the problem. This is on a live system so Im not sure what code is causing this. The server primarily runs osCommerce and vBulletin 3, all pages are pretty much PHP. I've tried increasing the memory allocation for PHP scripts from 8m to 40m, but this hasn't had an effect. Im willing to try other configurations as long as it doesn't disrupt my live websites too badly, to see where the bug might be. In regards to the system, it's currently running 1G of memory and is only using about half that at any given time. I will be upgrading the server to 3G of memory, however, Im not sure the physical memory is a limitation, apart from a memory leak somewhere.
