SEPM 12.1.4A Not processing Virus Definitions

Hi, 

I am running SEPM 12.1.4A from 10/30/2014 Sepm servers not processing the definisions. I have 5 SEPM servers  all are same (all using same SQL DB) all  showing same Virus definisions date on home tab.

-I have tried luall.exe I see the defnitions getting downloaded but they are not publishing on SEPM.

-I have tried downloading .JDB same issue,

-I have tried Uninstall liveupdate / Clearing the definions and run the luall.exe issue same.

-I have tried decrease Contenet revisons  from 20 to 1  nothing helped.. 

-Also changed FG_CONTENT Max File Size restricted to unrestricted file growth 

any other suggestions 

Thank you, 

Venkat..
