I am facing issue with CA Siteminder web agent 12.0.
Agent is getting crashed frequently.
I am getting below error in Apache error log.

Apache version: 2.2.26
This is semaphore and shared memory related error. Try the below steps to resolve this issue.
Detailed steps are outlined in the below KB.
The Error message states "Unable to initialize shared memory segment". It seems like this was raised a year ago under the same ID "UtxSupport".
Apache Error Log
It seems like we did suggest cleanups and that hasn't resolved the problem.
I'd also recommend looking at the following
1. tuning Shared Memory settings.
2. When the error occurs what is the state of Semaphore and Shared Memory Segments (Do you see a list OR there is none in the list).
If this is still not resolved, please open a CA Support Case.
