Stop LLAWP When Stopping IBM HTTP Server 2.0.47

The IBM HTTP Server 2.0.47 on Windows 2000 and 2003 crashes if the ibm_afpa_module and the Web Agent are enabled. If the ibm_afpa_module is loaded and a module registering an init function does not exit that function quickly, the apache.exe child process crashes with an access violation in LIBAPR.dll.

To solve this issue for versions of IBM HTTP Server v2.0.x, if there is an <IfModule mod_afpa_cache.c> line in the httpd.conf file associated with LoadModule ibm_afpa_module, comment out the following lines:

#LoadModule ibm_afpa_module modules/mod_afpa_cache.so

#<IfModule mod_afpa_cache.c>

# AfpaEnable

# AfpaCache on

# AfpaPort 8082

# AfpaLogFile "C:/Program Files/IBM HTTP Server 2.0/logs/afpalog"

   V-ECLF #</IfModule>

#<IfModule !mod_afpa_cache.c>

# Listen @@Port@@

#</IfModule>

By disabling the AFPA module, the IBM HTTP Server 2.0.47 starts properly.

Note: More information about the IBM HTTP Server limitation may be found by reading the document titled "Hang or crash of Microsoft Windows when Running AFPA and When Antivirus Software is Active" on the IBM Support site.
