I work on a University campus that deploys 100's of software titles to lab computers.  Since last summer, we have been using Config Man 2012 and upgraded to 2012 SP1 in early Jan.  Recently we started noticing 160GB hard drives filling up in locations that get most of our software.  When looking into it, the ccmcache folder has 50GB+ of data in it even though the cache size is set to 30GB.  I looked at the folders in the cache and many of them are from last summer when the apps were first downloaded and installed.  NONE of these apps are set to persist.  My understanding is that they should have been cleaned up automatically after 24 hours as space was needed.  Either way, shouldn't the cache folder be at or smaller than the cache size setting? 

I have talked to others that have seen similar problems with 2012 of the cache folder growing beyond the max, but they don't have the software load that we do, so they are not filling their drives.  If I manually tell Confi Man client to delete the cache files, I free up 50GB or more, but manual intervention isn't a great option.

Any ideas on where to troubleshoot this issue or what settings might be messed up that allows for this?

Thanks

Anyone help?

I can't help, but I can confirm I'm having the same problem.  Same thing University with a lot of software.  Just found a ccmcache folder of 75Gb when set to 50.  I've got a script to clean out the folder and am planning on updating some of my routine maintenance scripts for the labs to reduce the problem, but worried what it is doing to the standard workstations.  Using the clear cache button in the configuration manager applet deletes all the files which adds to the confusion.  It knows all the files and folders exist, but isn't properly managing them.  This particular machine had folder over a year old.

I have the same problem

Dow we have an answer yet?

Make sure to call Microsoft support (CSS) if the problem can be reproduced. They won't be able to fix it if they are not aware of it.

How much of this is software updates?  Like in 2007 software updates are not counted against the cache size:

"You can configure the location and amount of disk space that Windows Configuration Manager clients use to store temporary files for when they install applications and programs. Software updates also use the client cache, but software updates are not restricted by the configured cache size and will always attempt to download to the cache"
