There are a lot of bugs in the SEP 14 MP1.
Definitions stop updating until system is restarted with Endpoint Protection 14: http://www.symantec.com/docs/TECH236947
Netstat.db-wal is a multi-gigabyte file and continues to increase in size: http://www.symantec.com/docs/TECH239793
I have also seen to many of the clients in the SEPM that have problem with Sonar Status and Download Protection Status, i have not been able to find the cause to that.
