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 this bug report at http://bugs.php.net/?id=37483&edit=1
