Cause
The agent's transmitter.log shows a lot of "Address already in use (Bind failed)" errors that prevent it from opening a connection to the scheduler.
03/11/2019 16:21:55.946 IST+0530 1 TCP/IP Controller Plugin.Transmitter pool thread <Regular:1>.CybTargetHandlerChannel.constructConversation[:1198] - Error connecting to XXX_SCH:
cybermation.library.communications.CybConversationConnectBindException: Address already in use (Bind failed)
That usually occurs when all the ephemeral ports are in use or in a pending state (CLOSE_WAIT, etc).

Environment
CA Workload Automation Agent 11.3, Build 979, Service Pack 7
Redhat Linux 7.x
Redhat Linux 7.x
Resolution
So stopped the agent
./cybAgent -s
output of netstat -anp showed that there were 28k processes with CLOSE_WAIT for port 35004 help by PID 9667 for java. This is perhaps not allowing the agent to get any more ephemeral ports.
tcp6 0 0 x.x.x.x:59727 x.x.x.x:35004 CLOSE_WAIT 9667/java
tcp6 0 0 x.x.x.x:53710 x.x.x.x:35004 CLOSE_WAIT 9667/java
tcp6 0 0 x.x.x.x:46768 x.x.x.x:35004 CLOSE_WAIT 9667/java
tcp6 0 0 x.x.x.x:47232 x.x.x.x:35004 CLOSE_WAIT 9667/java
tcp6 0 0 x.x.x.x:60299 x.x.x.x:35004 CLOSE_WAIT 9667/java
killed the process ID 9667
kill -9 9667
Restarted the agent
./cybAgent -a
Now the autoping works fine
