3.      On the Applications Manager page, click the Agent Listeners icon. The Service Components page appears, containing a list of the installed agent listeners.

4.      In case if Agent Listener is down which could be because any service component failing and giving status “STOPPED WITH ERROR”, check for Workflow Agent Listener Service

5.      Workflow Agent Listener Service contains the service instances which are Workflow Mailer Service, Workflow Document Web Services Service, Workflow Agent Listener Service in either deactivated, verifying or aborted status.Restart ALL to activate them.

6.      In case a message that "Internal manager is down" is shown on restarting these instances ,check for the Internal Manager configuration .Login as sysadmin goto System Administrator>Concurrent:Manager>Administer. For the Internal Manager to be up and running,ACTUAL COLUMN must not be 0.

->We can manually kill processes FNDLIBR.EXE

->It can be stopped using CONSCUB utility as well
