systemd-logind: Failed to remove runtime directory

[Hellkeeper]

Hello,
today I noticed thousands of those Errors within m< /var/log/messages:

Unfortunately I was not able to find the Source of those Errors (googled the last 2 Hours ...)
Hope someone here can help me finding out what's wrong here?!

Run fuser -m /run/user/0 and see if that tells you anything.

Unfortunately you're not running CentOS, you're running an openvz container that's pretending to be CentOS and you'll need to ask your hoster for assistance.

Hi Trevor,
thank you for your fast reply!

[root@servername ~]# fuser -a /run/user/0
/run/user/0:
[root@servername ~]# fuser -m /run/user/0

Actually we *are* the Hoster ... and I just try to find out why this is happening in one of our Containers!
Not sure it the Problem is based on Centos Side or Virtuozzo - it it's Virtuozzo - I will open a Case with them.

thx
Andreas

systemd-logind: Failed to remove runtime directory /run/user/*****: Device or resource busy

I see this error many times in /var/log/messages.
Does anyone know tell me what this error means? And if I should worry about it?

[rodrigo-gomes]

This is the log of the last hour, in 1 hour happened 68 times.

[rodrigo-gomes]

Does anyone have any idea what this might be?
Is anyone reading this topic?

[TrevorH]

It means that a process is still using that directory. Do your users spawn background processes and leave them running?

I believe that yes, I use cpanel and host many websites.
My users ran php tasks with cron. We have php, mysql, apache, running on that server.

[TrevorH]

So, it's possible that they are still using the mount. Try running e.g fuser -m /run/user/987 (or whatever the mountpoint is in one of the more recent messages. You'll get back a list of PIDs and you can use ps to see what those are.
