On multiple servers running Windows Server 2022 Azure edition there is a constantly growing page pool, increasing the committed memory to its maximum. Task Manager Memory usage

Upon checking with poolmon, I noticed that the CLIP driver (ClipSp.sys) responsible for the licensing allocates more and more of paged memory, without releasing any of it. poolmon paging drivers

If we don't restart the systems for over 2 weeks, the page pool grows over 20GB

My question is, how best I can tell what does this driver do and why is it allocating that much memory?

Microsoft admitted that there is a memory leak. Currently there is a private patch they provide to customers that are affected. We tested the fix in our company and it does solve the problem, indeed.

The problem is solved in KB article ID - KB5027225 https://products.support.services.microsoft.com/en-us/topic/june-13-2023-kb5027225-os-build-20348-1787-d2b4b682-935f-4afb-8de0-2265ae7d67e9
