Fix ID: 3822263
Symptom: After installing or upgrading to 12.1 RU6 or 12.1 RU6 MP1a, blue screen errors occur on Windows Server 2003 R2 x86.

Fix ID: 3834919

Fix ID: 3849976
Symptom: The network utilization between the management server and client occurs is higher than expected due to the clients downloading a full set of virus definitions.

Fix ID: 3851761
Symptom: When a delta merge fails continuously, a large number of files are saved in the temp folder.

Solution: Handled this case silently as it is neither an error nor a security breach.
The IP address and fully qualified domain name of the source of the content is missing in the Windows Event Log for some content messages
Fix ID: 3827911
