Hi,
I'm currently having some issues with our Windows Server 2008 R2 File Cluster, where the System Process is chugging along @ 80-95% CPU, which I personally find strange. After 2-3 hours of this type of resource utilization, we experience a failover to our
passive node. After a few hours of user connectivity and build it the same thing happens again.
Using ProcessExplorer I have been able to identify the srv2.sys driver having massive amounts of threads being created, with several running at 10-15% + CPU utilization per thread. srv2.sys driver is for SMBv2 Connectivity from my research and troubleshooting
of these issues.
I have had a ticket opened with MS Premier Support and I have completed installing all of the latest srv2.sys file updates to the latest version for 2008 R2, but we still seem to be having the issues, although it is intermittently. One of these fixes was in
relation to enabling Access Based Enumeration to a certain level within your File System/Structure (http://support.microsoft.com/kb/2732618/en-us)
Other hotfix installed is http://support.microsoft.com/kb/2831154/en-us
We have users who run multiple image and CAD applications (Adobe InDesign, AutoCAD, MicroStation, Revit etc) across our network drives, as well as what I would call "standard" File Server access (word docs, spreadsheets, PDF's, powerpoint presentations etc).
We have ABE enabled across all volumes.
At the moment, I am praying for the server to again reach 100% CPU capacity due to the System Process using these resources.
What I was wanting to ask is, are there any known issues with using Access Based enumeration of Drives for users/applications that use these InDesign/AutoCAD like applications?
The reason I ask this is that when we experience this issue I notice more activity on our volumes that host these CAD/Design files, compared to when we experience a period of stability on the system.
I have read on a few articles regarding Microstation that if it is a specific version, that you should disable SMBv2 via registry to revert to SMBv1 for better use/stability. I am going down the path of disabling SMB2 for all users who use these CAD applications to see if this assists in resolving the issue, but I'm trying to explore all other options/potential issues to better configure our File Cluster
Looking for guidance on troubleshooting this issue further.
Thanks in advance.
