Previous Comments: ------------------------------------------------------------------------ [2002-04-03 19:35:48] agustinchernitsky@hotmail.com I got this error after aplying the lateste security updates on my win2k server. It works fine at the begginig but after 5 mins I get this error. It hangs all the IIS service. This doesn't happen in CGI mode. OS: Win2K Server Patches: SP2 + Lateste Security updates System: P3 @ 550 Mhz - 256 MB RAM PHP VER: 4.1.2. PHP Mode: ISAPI ------------------------------------------------------------------------ [2002-02-19 09:06:12] david@harksystems.com Nope, I am not using Zend Encoder or Optimizer. Just running plain PHP for now. ------------------------------------------------------------------------ [2002-02-19 08:52:53] pthiebaud@labeltechnologies.com Are you using Zendencoder? I have the same problem on a machine running Zendoptimizer with some pages that were Zendencoded. The server crashed every 20-30 request or so. I took off the pages Zendencoded and its working fine now... Seems that the problem stands there... ------------------------------------------------------------------------ [2002-02-01 15:41:48] david@harksystems.com I am getting an access violation in php4ts!zend_strndup + 0x2B + 0xA05CB1AD. It is reproducable after about 20 or 30 requests, but it isn't a certain page that causes it. A page refresh may or may not display the page without error. Eventually the server will no longer serve pages at all and only a reboot will bring the web server back. Stopping IIS just sits there attempting to stop the service. Details: Windows 2000 Pro with service pack 2 and all critical and security updates from windowsupdate.microsoft.com K6-2 500MHz with 192Meg RAM I have the exact setup on my machine using an Athlon 1.2GHz with 512Meg RAM without any problem. However on two machines with an AMD K6-2 (configured identically) the web server will stop responding to requests consistently. I have also tested this on my Dell laptop with an Intel PIII/700MHz 256 Meg RAM with same Windows 2000 pro w/sp2 and all updates without any problem. When the server does stop serving pages the DLLHOST.EXE process virtual memory size goes to the max for the machine. I have installed php as an ISAPI module. I have also tried installing PHP as a CGI and have the same problem. I have tested this with php 4.0.6, 4.1.0, and 4.1.1 and have the same problem in zend_strndup with all three. I am using the windows zip file from the php.net download page. Also I am using the Interbase extension. No other extensions are being used. I hope I included enough info here. Thanks. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=15333&edit=1
