Hello ,

i have upgrade my server to V14 and  same Clients to 14.0.1904 . 

Now its that some of the upgraded clients hangs or stuck in the weekly full scan.

The Files are random on clients

smc -stop not help

Only reboot  works as Workaround because its no solution

You may need to enable the logging to see where exactly it sits while scanning

How to log all files and directories scanned during On-Demand / Scheduled Scan with Symantec Endpoint Protection 11.x and 12.1

as you are already on latest version , its better to open up a case with Symantec

Do you use SIC (Shared Insight Cache)?

If yes, SEP 14 has bug with SIC and scanning >4Gb file.
