FsLogix - Unclean logoff causing locked files until server reboot

Much R 101

Problem is described by M4deman under unclean-logoff-causing-locked-files-until-server-reboot

It seems to have something to do with the 2009 version.
The latest version of FSLogix is installed whats-new

Description

After a user logoff, the "System" Process (PID 4) locks the following folders:

C:\Users\local_username\AppData\Local\Microsoft\Credentials
C:\Users\local_username\AppData\Roaming\Microsoft\Credentials

The user is completely logged of, according to Task Manager.

In the FSLogix Profile Log file I can see the following:

[07:53:55.601][tid:00000c90.0000ce44][ERROR:00000020] Delete profile failed for sid S-1-5-21-3364776539-3721753400-1968955100-1179, Cleaning up manually. (Der Prozess kann nicht auf die Datei zugreifen, da sie von einem anderen Prozess verwendet wird.)
The last sentence means that the process cannot access the file, because another process already uses it.

Also the whole "local_username" folder cannot be deleted:

[08:23:15.479][tid:00000c90.0000bcc4][WARN: 00000005] Failed to delete C:\Users\local_usename (Access is denied)
Access Denied

Does someone have any info on this behaviour?

Hello @Much R

Did you check affected user has full control and Owner over their FSLogix Folder and the VHDX files ?

Thanks

Hello,

Where is my answer from yesterday?
Why was this deleted?

How can I open a ticket at Microsoft now?

Thank you

Hello @Much R

sorry I was going to delete my comment as it wasn't helpful, and your comment is below mine, so it seems they were deleted together. I want to restore but it doesn't has this option.

FSLogix is supported for use with versions of Windows and Office that are still included in the Microsoft Support Lifecycle.

We are currently experiencing the same issue. The user VHDX is locked by system and can only be unlocked by rebooting the server.
Has Microsoft acknowledged this issue?

Currently using: 2.9.7654.46150

Did you activate the registry value HKEY_LOCAL_MACHINE\SOFTWARE\FSLogix\Apps\CleanupInvalidSessions (REG_DWORD, 0x1)?
Do you use Cloud Cache or not?

Also, maybe you can check with the frx command line tool if there are still some redirects pointing to the use VHDX file. You can then use that tool to delete them manually and detach the VHDX files afterwards using diskpart.

Hello,

we have the same problem.
We use on-premise terminalserver.:
Windows Server 2019
Citrix 1912 CU2 LTSR
FSLogix 2.9.7621.30127

I've tried the CleanupInvalidSessions RegKey, but it doesn't effect.
We don't use Cloud Cache.
FSLogix Configuration only local and not per gpo.
The frx command line tool dont show redirects pointing to the use VHDX file.
Permission are set correct. Users work correctly with the containers.
Luckily the problem occurs only randomly and not at every logoff.

In the FSLogix Configuration we include the group domain-users and exclude the domain-administrators.
Could it be a Problem?

Best Regards,
Marius

When this happens are you left with multiple <USERNAME>.original folders? I've seen it go as high as <USERNAME>.original11 before I just manually delete all the folders.

Hello Everyone, For the Group Policy Access Denied, once you get an affected user, could you please modify the following registry? There's no reboot required.

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileService\References\<SID affected user>
REG_BINARY: RefCount
Value: 0

We are having the same issue. We have an RDS environment and time to time users get logged in with Temporary profile, when I check the FSlogix logs I am seeing the following error - Failed to open virtual disk: \server\Profiles\S-1-5-21-26711-2174_user\Profile_user.vhd (The process cannot access the file because it is being used by another process.)
What we done to try resolve this or at least try find the cause and reduce downtime is, we have removed AV from all RDS host, we have created a script which logs out all users at midnight but issue is still occurring. We have a case opened with Microsoft but unfortunately there has been no resolution. Another issue we had is where users could not sign into their Outlook, teams, Office profile on the host. Has anyone else experiencing this issue and has anyone managed to resolve this? Any help or suggestion would be much appreciated.

This was the most active forum I found at a earlier time.
As mentioned earlier the 2105 preview and public version has solved problem for us.
Not sure what why fslogix still struggling in your environment.

I have tried to help much I can.

Did you change include groups?

I tried everything.
Nothing works. Today, the user's Outlook hangs, it didn't even shut down in the task manager. I ended his session and he couldn't log in again.

The problem is still there. Even though it doesn't show up as often in the latest version.

I currently have the issue on Server 2019 with the latest FSLogix version. I also tested with another profile solution (Citrix Profile Management) and the issue persist. I have the feeling this is a Windows Server issue and not necessarily related to FSLogix. Bare in mind that the underlying RDP components for Server 2019 are old. I'm wondering if the issue also happens on Server 2022.

I think so too. I didn't have this on Win2016, we just migrated to Win2019 and the issue is suddenly there.

It's not a really big problem for us though since we use Citrix Provisioning Services and all Citrix servers are clean again once restarted but a fix would be nice.

We too are facing this issue with a recent implementation. We have other sites setup with fsl running on the older versions without issues.

In addition to the black screen logons, we also experience users where they cannot connect to any 365 services. Appears to be related to aad/ssso in cominbation with fsl.

We have a case logged with MS, and still waiting to hear back from them..

Today I got the "The Group Policy Client service failed the sign-in" Access denied.

I found this workaround to at least let the user in again. HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileService\References\<sid affected user>
RefCount set the value to 0. Then when the user logged in a new local_username was created. Would it be possible to zero out this key at log off somehonw?

Also fix the deletion of the local folder. It is not always deleted and duplicates appear.

Also, in the latest version, sometimes a local profile was created and it is not deleted, ignoring the registry key to delete.

Has anyone tried to write a script for a temporary solution ? There will be a fix in November. https://learn.microsoft.com/en-us/answers/questions/229309/fslogix-unclean-logoff-causing-locked-files-until.html?childToView=568300#answer-568300

Why do you think there will be a fix in November? Can you link to anything to support that?

I have an open ticket with support now on this and they are pointing to our AV solution (SEP).

It's not AV. We used to run SEP on Windows 2016 without this issue. Now we are running Windows 2019 with Windows Defender and the issue is there. We have all the correct exclusions. I think it's more of an OS thing. Win2016 --> Win2019 and the issue started.
