Process (adcrpcs.exe) is leaking handles pretty steadily. After running it for a while, it shows a lot of handles open and not closing. Restarting the service addresses the issue temporarily.
It appears the handle leak is related to the process adcrpcs.exe opening a registry handle to HKLM\Software\Wow6432Node\Quest\AC\RpcServer\Configuration as these are being opened but not being closed.
The product defect with ID 554021 was identified. A temporary hotfix with the fix has been attached to this case as an attachment to be installed (InTrust 11.6.1.0003 Hotfix.zip). This fix should be included in the next release of InTrust, which currently does not have an ETA. The installation process requires having installed 11.6.1 before, and then it will be the same as if you were upgrading InTrust from there (refer to the Upgrade User Guide for more information)
