suggestion require to compress and use cmdctrl.db

We have PAM3.2 server with 100GB disk space. we have more than 300 Agent servers (including Windows , Linux , Database) and we are using RDP Relay, SSH Relay, DB monitoring , PCKSH and Run as privileged user features.we have noticed that cmdctrl.db which contains command control rules with usernames and hosts, getting larger in size day by day.
Is there any procedure to compress and use it. So disk size can be utilized. Please advice how exactly we can use the PAM server. We are worried about how to manage cmdctrl.db.

Thank you
