IIS 7.0 Worker process crashes on App Pool recycling since ISAPI redirector 1.Two.33

(The process ID does not match the one of w3wp.exe before the crash, strafgevangenis the one after the crash, so it seems a bit like when the fresh w3wp.exe is launched after recycle, it crashes and instantaneously another w3wp.exe is embarked).

Ter the ISAPI loom, following lines emerge 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 collective memory

The crashes and thesis loom lines didn’t emerge te ISAPI 1.Two.32.

Thanks for your reply.

I don’t think I’m using a web garden – I just have one application pool for all virtual hosts which use the ISAPI redirector, and that application pool consists of a maximum of 1 worker process (the default IIS values). It is set to be recycled every 1740 minutes, and ",disallowOverlappingRotation", for that pool is set to ",false", – I guess that means I’m using overlapping recycle (a fresh w3wp.exe is embarked which takes fresh requests, and after all old requests are finished, the old w3wp.exe will be stopped).

The 1 processor thread is the key. The problem I summarised with 1.Two.32 is that the collective memory is not protected by a OS semaphore, but an te process semaphore. 1.Two.33 wasgoed mean to address this by switching from an inprocess semaphore to a OS semaphore.

1. Make sure wij fallback to heap memory ter case collective cannot be created

Two. Fix collective memory create/open arguments

entries te case collective memory open fails.

If it fails you should have [warn] line, fountain balancer will not

function decently across numerous processes (will inwards each of the process)

but it shouldn’t crash.

implementation so fresh version will be out ter duo of days.

Thank you very much. I attempted the fresh version, and now when the Application Pool is recycled, the logs showcase thesis:

Thanks for looking at this promptly!

Could you please attempt the isapi_redirect_1.Two.34_5-dev_win32.zip

If this one crashes wij’ll have to add some override to collective memory so wij can fallback

to heap one and bypass memory corruption which seems to occur at IIS worker recycle.

Eg, if connection to one backend is violated each process will

have to detect that by itself. Collective memory permits that if

one worker process detects that a backend is down other won’t

have to go trough the lengthy process of discovering that.

The ultimate solution would be to begin a separate controller

process, but that’s very likely something for the future.

wij should have a directive to disable collective memory usage, and

think I’m going to add that option for 1.Two.34 anyhow.

Not deny that, just thinking out aloud, also bot asking myself if there is any reason to run a Four process web garden. The only benefit I can see is that if 1 process dies there will be other process to proceed processing.
