In most of the cases ,a custom Stop / Start scripts are used to restart the web servers with Siteminder Agents (Apache ,Iplanet ,IBM HTTP server ...) .
Some of these shutdown scripts uses the Kill -9 to terminate the LLAWP process in case it took longer then expected to shutdown.
The sempahores and shared memory must be cleaned up for the LLAWP process if kill -9 before starting the Web server and fork a new LLAWP .
This can be tricky if you have multiple Virtual Hosts configured with the agent as you will need to determine what semaphores / Shared memory to clean up that is linked to the LLAWP process in question.

Below is how to correlate the LLAWP PID to the created semaphores and shared memory.
