ZCM 10.2.1 at SLES 10 SP2
OS: Windows Server 2003 EE R2

Today I found that free space terminal server system disk was ended. I found folder in ZCM Agent installation, that has big size. It is "C:\Program Files\Novell\Zenworks\bin\handlers\UserCache". It size over 4 GB. As I understand in this folder stored GPO files.

How I can limit size grow of this folder?
