CcmCache limit and old antimalware delta packages

I am noticing computers that receive antimalware definitions through SCCM Software Updates are retaining these antimalware related packages inside the C:\Windows\ccmcache beyond the 5GB limit that I have set in the client settings. There are packages that are over a year old. Why does the client not remove these packages. I found this thread on sccm cache https://social.msdn.microsoft.com/Forums/en-US/856113c3-37fe-46d2-8e9e-ea3863d06dba/sccm-client-cache-folder-size-growing-instead-of-limit-set?forum=configmgrgeneral. It is stated that updates are not figured into the ccmcache size limit. Is this true, or still true? I had a server that was getting low on disk space, but I was able to free about 20GB of old antimalware definition packages. It would have been nice if the client would have just done that for me.

    Here is an answer to your question that hopefully you find helpful!

    It is stated that updates are not figured into the ccmcache size limit. Is this true, or still true?

    Yes, software updates are not restricted by the configured cache size and will always attempt to download to the cache.

    Here is an article for reference: Configure the Client Cache for Configuration Manager Clients

    I haven't seen that issue before. We also set our CCMCache to a minimum of 25GB and have a Baseline for grooming the cache, which cleans up old updates, so I'd never see any content that old in our cache.

    Thank you for your responses. It would be nice if the client was able to clean up these old AM Delta updates, but I guess I will put together a script solution. The baseline configuration is a good way to deploy that. Thanks again!
