Thank you very much. I tried the new version, and now when the Application Pool is recycled,
the logs show these:

[Sun Mar 18 12:10:36.324 2012] [4144:6216] [error] jk_shm_open::jk_shm.c (220): Failed to
map shared memory JK_TTWEBINFO_DYNDNS_ORG_8_JAKARTA2_ISAPI_REDIRECT with errno=87
[Sun Mar 18 12:10:36.337 2012] [4144:6216] [error] init_jk::jk_isapi_plugin.c (2801): Initializing
shm:(null) errno=87. Load balancer will not work properly!

But w3wp.exe doesn't crash anymore, so I think it is fixed. (I'm wondering now why mapping
the shared memory fails..)


Thanks,
Konstantin Preißer
