From: jneill at gamedaytv dot com Operating system: Windows 2003 SP 1 PHP version: 5.1.4 PHP Bug Type: IIS related Bug description: PHP5TS.DLL causes w3svc crash and application pool termination Description: ------------ We have been successfully using PHP 5.1.2 for several months in our server environment. Only upgrading PHP to 5.1.4, with no other software upgrades, has resulted in frequent w3svc crashes and subsequent application pool terminations. The system log includes such errors as: --- A process serving application pool 'Site1' terminated unexpectedly. The process id was '5796'. The process exit code was '0xc0000005'. A process serving application pool 'Site2' terminated unexpectedly. The process id was '5212'. The process exit code was '0xffffffff'. A process serving application pool 'DefaultAppPool' terminated unexpectedly. The process id was '5824'. The process exit code was '0xc0000005'. --- We have run the IIS Diagnostics Debug Diagnostics Tool on these crashes, which has resulted in the following report for each crash: --- Type of Analysis Performed Crash Analysis Machine Name S76217 Operating System Windows Server 2003 Service Pack 1 Number Of Processors 2 Process ID 4736 Process Image c:\WINNT\system32\inetsrv\w3wp.exe System Up-Time 0 day(s) 04:18:05 Process Up-Time 0 day(s) 00:31:08 Thread 16 - System ID 2612 Entry point msvcrt!_endthread+3b Create time 5/16/2006 5:31:43 PM Time spent in user mode 0 Days 0:0:0.0 Time spent in kernel mode 0 Days 0:0:0.0 Function Arg 1 Arg 2 Arg 3 Source <Unloaded_php5ts.dll>+265c80 02a28890 00000000 00000000 msvcrt!_endthread+ab 029e7580 00000000 00000000 kernel32!BaseThreadStart+34 77bcb35a 029e7580 00000000 In w3wp__PID__4736__Date__05_16_2006__Time_05_31_45PM__95__Second_Chance_Exception_C0000005.dmp an access violation exception (0xC0000005) occured on thread 16 when another module attempted to call the following unloaded module: php5ts.dll. --- -- Edit bug report at http://bugs.php.net/?id=37483&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=37483&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=37483&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=37483&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=37483&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=37483&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=37483&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=37483&r=needscript Try newer version: http://bugs.php.net/fix.php?id=37483&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=37483&r=support Expected behavior: http://bugs.php.net/fix.php?id=37483&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=37483&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=37483&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=37483&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=37483&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=37483&r=dst IIS Stability: http://bugs.php.net/fix.php?id=37483&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=37483&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=37483&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=37483&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=37483&r=mysqlcfg
