Error: "Shutting down SharePlex: HostID not found from CPA/Lib/LicenseGetMachInfo"
Description

sp_ctrl fails with a message 'sp_cop not working or TCP/IP port not set-up' .
In the event_log file, there is an entry like:
Error: Shutting down SharePlex: HostID not found from CPA/Lib/LicenseGetMachInfo [sp_cop/

sp_cop and replication keeps working fine, but cannot launch sp_ctrl.
Cause

Failure of sp_cop due to memory leak inside of the AIX libraries used by sp_cop to run odm and/or running out of shared memory while checking the license. This will cause issues with lauching sp_ctrl.
Resolution

Workaround:
Restart sp_cop
Additional Information

1) To check for a memory leak you can periodically execute the command ps v <pid_for_sp_cop>, and then check the size:

2) $ ps v 69406
PID TTY STAT TIME PGIN SIZE RSS LIM TSIZ TRS %CPU %MEM COMMAND
69406 pts/7 A 0:02 186 23288 23964 xx 1251 676 0.0 0.0 /splex/61

3) If the leak is occurring, the SIZE value will increase every 2-5 minutes.

This problem was worked-around in 5.3.4 by calling odm only at startup and when the license changes
