Issue/Introduction

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.X

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
​

If it does not work as expected (as the example above), you can disable http manually through Windows registry:

• Launch RegEdit;
• Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP;
• Change the value of "start" to 4, which means disabled;
• Reboot your computer.
