We are suddenly experience major problems on all of our four productionservers. We are running four IIS 6 servers on Win 2003 Server which are connected with isapi_redirect (ajp13) to four tomcat 5.5.12 which is mapped 1 to 1. They have been runnning fine in at least some month and suddenly the IIS application pools is crashing for us and we have no idea why, tomcat is running fine and we cant se any problems. The is a typical event from one of the iis server event log: ----8<---- Event Type: Error Event Source: Application Error Event Category: (100) Event ID: 1000 Date: 2007-02-07 Time: 19:48:02 User: N/A Computer: SE05WWW02 Description: Faulting application w3wp.exe, version 6.0.3790.1830, faulting module ntdll.dll, version 5.2.3790.1830, fault address 0x0002f583. ----8<---- We have run DebugDiag and this is a snippet from that, below, and the only clue we can find is that the following: isapi_redirect!TerminateFilter+89af 01027884 00000000 6a6b8266 isapi_redirect+8406 00000048 010278a0 0000000a
To me it looks like the method TerminateFilter in isapi_redirect is in someway crashing... And we have looked in the tomcatlogs, iis logs, event logs and can't se why this is happening. ---8<--- Type of Analysis Performed Crash Analysis Machine Name SE05WWW02 Operating System Windows Server 2003 Service Pack 1 Number Of Processors 4 Process ID 9152 Process Image c:\WINDOWS\system32\inetsrv\w3wp.exe System Up-Time 04:07:33 Process Up-Time 02:23:09 Thread 5 - System ID 9188 Entry point w3tp!THREAD_MANAGER::ThreadManagerThread Create time 2007-02-04 19:11:05 Time spent in user mode 0 Days 0:0:0.468 Time spent in kernel mode 0 Days 0:0:0.421 Function Arg 1 Arg 2 Arg 3 Source ntdll!RtlpCoalesceFreeBlocks+36e 01091018 01741028 00d8ec68 ntdll!RtlFreeHeap+38e 00260000 00000000 0108f010 msvcrt!free+c3 0108f010 01027780 00000000 isapi_redirect!TerminateFilter+89af 01027884 00000000 6a6b8266 isapi_redirect+8406 00000048 010278a0 0000000a ---8<--- Any input is most welcome, we have no idea where to look or where to search for an error. So any suggestions is of great help... I attach the full debugdiag result.
