FSlogix BSOD frxdrvvt.sys on Windows Server 2022

Question

Hi,

Anyone else seen this yet?

• Windows Server 2022 standard install.
• Microsoft FSLogix 2210 hotfix 1 (2.9.8440.42104)
• User profile disk

When I search for e.g. *.PDF in "C:\Users\username" (Within an FSlogix mounted profile) all is well and I get my results.

When I search for e.g. *.PDF in "\\127.0.0.1\C$\Users\username" (Within an FSlogix mounted profile) the system freezes and bluescreens. This happened first when I searched the user profile of a remote system. Browsing the user profile doesn't cause a bluescreen, but a search does.

BSOD info:

KMODE_EXCEPTION_NOT_HANDLED 0x0000001e ffffffffc0000005 fffff8064df67ab2 0000000000000000 0000000000000048 frxdrvvt.sys frxdrvvt.sys+7ab2

Hello there,

Have you tried the given troubleshooting steps in the following link https://learn.microsoft.com/en-us/fslogix/troubleshooting-old-temp-local-profiles

An NTFS file system blue screen error may also occur if the system disk has errors or bad sectors.

I would recommend that you run a full-fledged chkdsk /r on the disk in case corruption is found.

We can find corruption by running chkdsk <drive_letter> or check id the dirty bit is set using the command fsutil dirty query <drive_letter>.

If corruption is detected, I recommend running a chkdsk /r. Why i would recommend this is simple, if chkdsk finds some files in lost clusters, it would attempt to recover them and would put them in a folder titled found.xxx where xxx=001,002 etc.

The below thread discusses the same issue and you can try out some troubleshooting steps from this and see if that helps you to sort the Issue.

Hope this resolves your Query !!

Hi,

Nobody seems to experience the same issue, however I have created a ticket with Microsoft and they just confimed they were able to recreate the issue with ease.

So I'm happily awaiting a root cause analysis and hopefully a fix :).

Answer 4

Hello,

we are facing a similar issue, but in our case the terminalserver get a BSOD when we copy files/folders to a users profile under "C:\Users\username".
we are also getting the BSOD when searching locally in "C:\Users\username"
nothing happens when we copy the files/folders from another client to "\<terminalserver>\C$\Users\username"

a fix would be highly appreciated!

Hi,

Microsoft tested my scenario and were able to recreate the BSOD. They have it fixed now and it should be in the preview version of FSlogix. I haven't been able to get it though. I filled in everything to be allowed in the preview program, but that was 2 weeks ago already ... .
