Previous Comments: ------------------------------------------------------------------------ [2003-12-08 06:00:30] jim at ernie dot demon dot co dot uk I've got possible same problem with 4.3.4 using FastCGI on IIS 6, Windows 2003 server. I am getting intermittent crashes with exception error returned back from php.exe. Error reported: Application Error The instruction at "0xYYYYYYYYY" referenced memory at "0xZZZZZZZZZZZ". The memory could not be "read". The fastCGI wrapper for IIS returns a 503 "Server too busy" error: "Server Error, unable to connect to fastcgi server." I have checked the source for this error and located it in isapi_fcgi.cpp, line 373. See http://www.caraveo.com/fastcgi/fastcgi-0.6.src.zip for source. This confirms dietrich report. FastCGI wrapper is probably unable to connect to stale php.exe process after php.exe has caused an exception error. To repro statistically, run Microsoft Web Application Stress Tool from another client and reference the fastCGI server. This is just to provide enough page hits to repro error as it is intermittent. I get ~20% 503 errors returned from the tool and corresponding php.exe application errors on server console. Note: This error occurs with pages that do not use fsockopen or pfsockopen. All pages use mysql_pconnect. I have tested with mysql_connect - same problem. MySQL version is 4.0.16-nt. DB is resident on the same server as fastCGI/IIS server. This is just (external dependency) information, not necessarily the source of the problem. ------------------------------------------------------------------------ [2003-12-07 12:17:41] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip Just try the snapshot and report whether this is fixed or not.

I've updated to the latest stable Windows build, and applied Edin's patched php4ts.dll. The example script I gave still reproduces the crash. The text of the Application Error alert is: The instruction at "0x100108b4" referenced memory at "0x00000000'. The memory could not be "read". Then, as before, I get the FastCGI error: Server Error, unable to connect to fastcgi server. Thanks for any help in fixing this! ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
