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 @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.

There is an interesting line in the release notes for the 2201 Preview version:

FSLogix now correctly handles cases where the Windows Profile Service refCount registry value is set to an unexpected value.

Hello,
I'm thinking about upgrading FSlogix in our AVD infrastructure to latest version, just in case it fixes this problem.
Can I just download the latest installer and run it? Do I need to do any changes prior or after the upgrade??

Hi

We also have the same issues with the following environment

Windows server 2019 + latest updates
Citrix 1912cu3 vda
Fslogix 2105
Ivanti environment manager for policies

We see the local_username folders left behind.which cannot be removed and see entries in logs for either folder not empty or access denied when it’s trying to do a cleanup.

We are also using cloud cache and sometimes profile containers appear to be having some corruption as we will see some failures at logon where drive mappings etc won’t work and ivanti policy fails to load for the user session. This is intermittent and you can log on and off multiple times and not see it but suddenly it will happen for a user.

We are using the cleanupinvalidsession key and I read in an old article this was not supported with cloudcache. What is the reason not to use it with cloudcache and is there any impact using it?

We don’t seem to have many issues with logoff or container locks but we have had issues with logons which required a server reboot to fix.

Has anyone had any success with the recent preview build of 2201? to resolve any of these issues.

Thanks

Are you having issues with users signing in such as hanging? I'm also encountering this issue.

I found that it is related to the LogonUI.exe process hanging on something I've had Microsoft review logs / troubleshoot they can't find anything. I've also had Citrix troubleshoot and sent CDF logs and still nothing they can see.

I've written a script that terminates the LogonUI.exe process and it has fixed our problem but it's definitely a "hack" fix until we figure out what is actually happening...

Cheers.

We are not really having issues with logins hanging but we are having issues with local_username staying on disk under c:\ and also under %programdata%\fslogix\cache

All of these locations at log off should be clear. This happens on random servers too, some days servers have no issue and other days a few end up with lots of these folders left. We also have some issue around profile containers corruption although not that much so far. We do have intermittent issues around ivanti environment manager user virtualisation also not running for a user at logon, usually a logoff and re-logon resolves that one so it could be a timing issue.

We are looking at nightly checks now as some have commented on here and rebooting any servers that have local_username folders left when there are no sessions.

@ MichealThompson-2636 - Are you terminating LogonUI.exe during the logon process or logout? VDI or Shared Environment?

Hi Felixo,

Yes during both Logon & Logoff stages it would hang and that task would be the cause.

This has since been determined to be an issue with Citrix and was resolved in version 2203 LTSR.

Thanks
