> WIN64/AMD64 ISAPI Redirect
> 
> isapi_redirect 1.2.20 with shared memory patch

Hi Mladen, 

We are having similar sort of issue on Win32 Platform. I will explain in 
detail. 

Environment
We are running MS Application Center Load Balanced Web Server Farm with 3 nodes
running IIS 6 in Worker Process Isolation mode. The Tomcat/JBoss runs on two
separate Servers (again Load Balanced via Application Center). The Web Server
Farm is running 5 Websites. The JK ISAPI redirector version is 1.2.19 and is
configured on per site basis.

Problem
Everything works fine except when the application pool undergoes recycling, the
website using that application pool wouldn't work. Recycling application pool
again, restarting website wouldn't help. The request to that website gets 404.2
and 404.3 in IIS logs. The 404.2 indicates that JK ISAPI is locked or access is
denied to the JK ISAPI. The only way to get it working again is to do an
IISRESET which affects all other websites and disconnects all the users
connected to those websites. Its very frustrating as the whole purpose of IIS 6
running in worker process isolation mode is defeated.

The JK Logs shows the following 
[Wed Nov 15 17:25:41 2006] [1228:4924] [error] jk_worker.c (256): failed to
create worker lbworker

The windows eventlog would show the following: 
Event Type:     Information
 Event Source:  W3SVC
 Event Category:None
 Event ID:      1074
 Date:          15.11.2006
 Time:          06:56:36
 User:          N/A
 Computer:      xxxxxxxxxxxxx
 Description:
A worker process with process id of '6308' serving application pool 'xxxxx' has
requested a recycle because the worker process reached its allowed processing
time limit.  

We didn't have any issues with the earlier version of JK which was 1.2.08. I
have a strong feeling that this has to do with the shared memory problem. 

Please let me know if you need any further information, config files or log 
files.
