From the controller log what does the following error mean?
Oct 16 03:02:44:850  Controller: sockCompleteConnect: socket disconnected
Oct 16 03:02:48:885  Controller: Port dropped: cdm 48008
The error occurred several times before cdm configuration was gone. cdm stopped collecting data at 16 Oct 3am.
Release : 20.1
Component : UIM - CDM WITH IOSTAT
target OS: Solaris 11
robot version: 7.93
cdm version: 6.42HF
You may want to try upgrading the robot to take advantage of any fixes.
Any change after setting the controller first_probe_port to a different/higher port than the one being blocked/address already in use?
Please also check what other process/app might be using the port by running:
netstat -an|grep <port>
You can try setting the controller first_probe_port to 48010.
Also as I mentioned, error code 125 indicates 'address already in use.'
Check for core dumps too - and make sure there is not security software blocking the probe/process/port. Sometimes security software blocks ports when hey are not previously whitelisted, e.g., illumio.
Also please check the Solaris Firewall.
