Hi all,

I have a system with Windows Server 2008 32 bit, IIS 7.0, Java 1.7.0_03, =
Tomcat 7.0.26 and the ISAPI redirector.

Since I updated the ISAPI redirector from 1.2.32 to 1.2.33, it seems =
that each time when IIS tries to recycle its application pool, the IIS =
worker process (w3wp.exe) crashes in isapi_redirect.dll. In the event =
log, an "Application Error" of w3wp.exe is logged (here is an English =
translation):

Faulty application w3wp.exe, Version 7.0.6002.18005, time stamp =
0x49e023cf, faulty module isapi_redirect.dll, Version 1.2.33.0, time =
stamp 0x4f59be7d, exception code 0xc0000005, error offset 0x0002bb16, =
process ID 0x10f0, application start time 01cd0336e5b7824a.
(The process ID does not match the one of w3wp.exe before the crash, nor =
the one after the crash, so it seems a bit like when the new w3wp.exe is =
launched after recycle, it crashes and immediately another w3wp.exe is =
started).


In the ISAPI log, following lines appear when w3wp.exe crashes:
[Fri Mar 16 06:37:38.402 2012] [4336:6828] [error] =
ajp_worker_factory::jk_ajp_common.c (3006): allocating ajp worker record =
from shared memory
[Fri Mar 16 06:37:38.417 2012] [4336:6828] [error] =
wc_create_worker::jk_worker.c (150): factory for ajp13 failed for =
worker1
[Fri Mar 16 06:37:38.426 2012] [4336:6828] [error] =
build_worker_map::jk_worker.c (261): failed to create worker worker1
[Fri Mar 16 06:37:38.434 2012] [4336:6828] [error] =
extension_fix::jk_uri_worker_map.c (554): Could not find worker with =
name 'worker1' in uri map post processing.

Any idea what these lines could mean / that caused them? Note that it =
seems that after the crash (when a new w3wp.exe is created), pages are =
served fine again (though I do not know what happens with request that =
are made exactly in the time when IIS resets the app pool).
The crashes and these log lines didn't appear in ISAPI 1.2.32.

I think I read somewhere in the thread "Issues with the tomcat connector =
(On W2k8 + IIS7.5)" about some change in the ISAPI connector which has =
to do with shared memory, but I'm not sure.

Thanks!
