Hmmm,

I didn't know that. Since KB3216755 can also be installed on Server OS (which many did). But you are probably right and I checked the information on the system.data.dll and the versions are the same in both KB's which means the issue is still there.

We do not have any repository on Backup Server. This Hotfix is installed on repository servers only. So should not be a problem.

Yes, I installed this hotfix last week as well on all repository servers. I am not sure this hotfix address to solve this issue but after installing, no server hang was experienced any more.

I got another issue (compact job still failed but no server hang any more and the error is different) after installing this hotfix and working with veeam support to address it.

Sorry but this is kind of off-topic. The RPC issue has nothing to do with the REFS issues or the MS hotfix.

About the original RPC issue: Veeam support instructed us to create a FileCacheLimitPercent setting in Registry and set it to 0. Since then we had no issues. We are still not 100 % certain that it is finally solved but we are optimistic...

anyone still having issues that veeam repository servers with refs used 100% CPU and sometimes freezes then??

as far as i understand every hotfix should be included in the latest cumulative hotfixes, as my server has build 14393.1358 it should have the fixes allready in?

it's a virtual proxy, and locked up all 8 vCPUs, even VMware console does only display blue screen, no logonscreen there...

I don't believe any ReFS-related hot fixes have made it to Windows Update yet.
