Does anyone know how to troubleshoot this problem?
After reboot the opscenter, it still cannot connect to Master Server.
Check this thread
Thanks In Advance
The Opscenter server just install Anti-Virus (Mcafee v8.8) Does it any impact towards opscenter?
Try to disabled Antivirus service and check ?
Please try to provide some more information like OC version , NBU version , if multiple master servers are added , If it's not connecting to only one master server , Is it partially connecting , if yes which data collector is failing etc .....

You can disable / enable data collection for one or more masters from the Settings / Configuration / NetBackup tabs within OpsCenter.
You can also click on the Data Collection Left Navigation Item on the Home Page after login for OpsCenter.
If you see a master reporting offline, partially connected, etc... click on the name of the master.
Then at the bottom of the screen, locate the Data Collection Tab, and click on it.
You will see all Data Types listed for collection for the master you have clicked on previously.
Scroll though the items, and see if there are any failures reported.
If so, please reply with the failure message, and the Data Type the failure is occurring on.
Also, you may want to check the host properties of the master, under the server section. You may find, an admin may have removed the OpsCenter hostname from the list of additional servers, or if the master is 7.5.x.x there is now an OpsCenter Tab.
If you have any questions, please let me know.

After reboot the cluster node and switch over the active node. The Netbackup and opscenter resume normal. symantec engineer said that nbsl hang and some clients/servers which is not reachable, it could also cause nbsl unresponsive due to excessive sockets/communication channel being occupied.
Does it any technote support it?
It depends on many factors....
There are different versions of NBSL at each version of NBU.
Depending on your Master Version... it could be effected by many things, one being SLP duplications.
I highly recommend upgrading your OpsCenter host to 18.104.22.168, and then very your master server version, and if there are any Engineering Binaries installed on the master.
If the issue persists frequently, you will want to revisit the case with support and verify if there are any EEB's available for NBSL at your Master Version.
