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,

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.

From what remember its part of the windows search issue so it will be resolved in normal windows monthly updates but no time frame on when.

This service is not running for us and the problem remains.

What does the search service have to do with it? This problem is over a year old.

I see that the problem is robocopy.

Honestly I am not sure. We have this issue and we also have the issue with folders not being deleted.
My case was put on hold as its related to windows search. If you arent using windows search then not sure.

If you do not use windows search is your outlook searches slow and wrong? Outlook needs windows indexing / search for its search features other wise its normally pretty slow.

We are not using Windows Search either, and search is fast, its using online search. Windows Search is disabled for us.
No issue with Outlook, We had to run search for Windows 2016 servers, but not for 2019 servers.

Who told you it will be fixed with monthly update?

Interesting about the search I may have to try that then. I mean search works without indexing and windows search but its way better with it on.
My case with Microsoft on my issues that are similar to this is on hold due to it being fixed with windows search for a monthly update.

I have an environment running Windows 10 Multi-User in Azure on 20H2 release, and previously I was using FSlogix version 2004 with 19H2, which worked out as intended according to accomplishing not having locked disks.
Now on 20H2 the issue has been re-introduced with both version 2004 and 2009 HF_01 (2.9.7654.46150).

I will try out the new 2105 Public Preview!

Just tried out the 2105 Public Preview and it partially fixes the issues we're seeing. The System (PID 4) process is no longer holding onto anything, but the lsass.exe process does.

Thanks for feedback Ryan.
In our scenario, this 2105 version from MS seems to have solved problem completely, with crash of the Fslogix service and disk retries / logon etc.
According to csrss issues you refer to, check out this Citrix forum and what Balaji Muthukrishnan mention.

Could this be a fix for "rest" problem you refer to?

The issues we saw were on Windows 10 20H2 single-session (random) desktops. Windows event logs and a procmon capture showed profile name mismatches and failed vhdx creation attempts. So at the suggestion of MS Support we adjusted our VHDNameMatch and now things appear to be working a lot better.

We have no antivirus scanning the fslogix directory. And I believe that this only is a solution when you use cloud cache?

Hi!

I am using Windows Defender with the exclude directories, and I am experiencing this situation.

Any workaround?

It is a WVD with NV v3 vm in production. I cannot restart during the days.

CleanInvalidSessions = 1 ?
GPP = Update ?
Antivirus = ?
Downgrade to 2004 Fslogix version ?

Anyone has a gold bullet ?

Thanks
Denilson

Downgrading to FSLogix 2004 won't fix the issue however it would drop down the frequency of the issue.
We are using WS2019 + FSLogix 2004 for office containers. We have a case with MS from past few weeks but they have no answer to this.

Thanks,
Nirmal
