Issue:
We had a server this weekend that our Linux team reduced the number of cores per cpu (reduced the number of cores from 4 to 2 to make this a 2 socket system using 2 cores per socket for a total of 4 CPU Cores).

After they completed this process they then rebooted the server. When we tried to run a job to the agent we got the below message in the logs

CAUAJM_E_10229 Communication attempt with the CA WAAE Agent has failed! [:7520]

Resolution:
There was an entropy issue. The valve was below 300. Increasing this value resolved the issue.
