Yes I have, but TAC investigation may not the fastest, so I want to try here, unfortunately, it should new findings and no one knows.
Here is the solution from TAC, and I accepted this is the solution, also performed in production environment, FYI:
Check mgha file, if bytes only "4" that should be file corrupted.
[Expert@cfXXXX:0]# ls -ltr /opt/CPsuite-R80.40/fw1/log/mgha
Sample output:
drwx------ 5 admin root 4096 Dec 7 14:29
Remove the corrupted file in both Primary & Replica Management Servers
Delete "/opt/CPsuite-R80.40/fw1/log/mgha"
Check the Sync status again
