Issue:
CA Process Automation is unable to start ActiveMQ after numerous retries.

Error message in c2o.log:

ERROR [com.optinuity.c2o.c2oserver.ServerManager] [ Initialization] Unable to start ActiveMQ after numerous retries, hence shutting down the PAM server...
Environment:
CA Process Automation 4.3.03
CA Process Automation 4.3.02
CA Process Automation 4.3.01
Cause:
Somehow port 80 is being used and preventing ActiveMQ to start up properly.
Resolution:
If it is a System Process PID 4, you need to disable the HTTP.sys driver which is started on demand by another service, such as Windows Remote Management or Print Spooler on Microsoft Windows.

Command to identify if Port 80 is in use:

netstat -ano | findstr ":80"

See example below:

Command to disable the HTTP.sys driver:

net stop http
