Agent creates many files (private keys)

Hi

MEDC 10.0.706

DC agent creates many files (private keys) in folder C:\ProgramData\Microsoft\Crypto\SystemKeys on all computers (workstations and servers), where agent installed.
During every one session from computer to DC server DC agent create 10-12 private keys and not delete them. 
Since the beginning of the year this folder contains 60 000-70 000 private keys on servers and 30 000-40 000 private keys on workstations and over 700 000 keys on Distribution Server !!!!!
