Make sure the DSVA's are upgraded to the latest version. Usually you have to download the RHEL6 or 7 (depends on your Deep Security version) x64 agent. Then you will have an option to upgrade the DSVA's from their Overview screen under actions.
If the DSVA version looks different than all the other agent versions in your software update screen, this is most likely the cause. Check the readme for your DSVA version to see what type of RHELx64 flavor it wants....Deep Security 11 is RHEL7x64
