Squid Posted August 3, 2015 Share Posted August 3, 2015 Using 6.1 rc-2 Intermittently I'm getting this message logged: Aug 3 17:10:14 Server_A kernel: unregister_netdevice: waiting for lo to become free. Usage count = 1 Now, I don't particularily care about the message, but what's annoying me is that if I have a SSH session open to the server (and I almost always do) is that it's also showing up there. Very annoying if I'm in the middle of something with nano, and the message pops up in the middle of my edits. Never noticed anything of the sort happening pre rc-2 1 Quote Link to comment

SpaceInvaderOne Posted October 19, 2015 Share Posted October 19, 2015 im getting same message Quote Link to comment
mudboy Posted November 5, 2015 Share Posted November 5, 2015 Also seeing this after I deployed a docker container and removed it. container was syncthing from jfgardim if it matters. running 6.1.3 Quote Link to comment
ysss Posted November 15, 2015 Share Posted November 15, 2015 I shouldn't have upgraded to 6.1.3... I'm getting this error, some docker container could crash the whole system and SABnzbd runs super slow on this. Quote Link to comment
Squid Posted November 15, 2015 Author Share Posted November 15, 2015 I shouldn't have upgraded to 6.1.3... I'm getting this error, some docker container could crash the whole system and SABnzbd runs super slow on this. On my system its harmless (annoying since it shows on any putty session, but harmless). But, on a quick and dirty google search, it looks like it could be docker related NFS related within an LXC container (docker IIRC leverages LXC containers) I am curious if when the message appears for you if that's when one of your containers crash. (Mine never have at all) Quote Link to comment

(Mine never have at all) I don't use NFS on any of my dockers... I'm not sure what happened with the docker that crashed, it started because I was getting 1/10th of my regular speed on SABnzbd (hurricane's?) and I went to reactivate my long-dormant NZBget container. It needed an update, so I ran that... well that thing ran for eternity and crashed the web interface, and when I logged into the server via ssh, I saw the dreaded errors in the log and teh system was unresponsive, so I rebooted after that. I know, it wasn't 100% conclusive, but that's what I saw... Quote Link to comment
danioj Posted December 29, 2015 Share Posted December 29, 2015 To add something to this old (sort of - ~4 weeks ) thread but I have this msg now too. kernel:unregister_netdevice: waiting for lo to become free. Usage count = 1 This happened shortly after I clicked "Update Applications" under the Community Applications Tab. While the web page was locked while the update happened the console started receiving the above msg. I decided to end the browser session (as it was taking too long anyway) that was running the update and the msg stopped. I have had no other instance of this msg. I am running 6.1.6.

guyonphone Posted December 31, 2015 Share Posted December 31, 2015 Happening to me too Quote Link to comment
anthropoidape Posted January 2, 2016 Share Posted January 2, 2016 Has this been explained yet? I have been getting this message the last few days. I just got it with no dockers running. It doesn't seem to have any effect other than to mess up the display on Midnight Commander if I happen to be using it. Quote Link to comment
danioj Posted January 2, 2016 Share Posted January 2, 2016 What do you think everyone, is this an issue worthy of reporting formally? Quote Link to comment
Squid Posted January 2, 2016 Author Share Posted January 2, 2016 The problem is that it is extremely intermittent. And even when it does appear, it is harmless. The only time I believe that I've seen it since I started this thread is a couple of weeks ago when I was stopping the array (stopping docker). You can make a formal defect report all day long, but ultimately you're going to be posting "Yeah, this error popped up, yeah nothing averse happened, and yeah I have no idea how to replicate it or why it showed up, and could you please fix it Quote Link to comment
CHBMB Posted January 2, 2016 Share Posted January 2, 2016 FWIW: I've seen this too, and I ignore it.. Quote Link to comment
exist2resist Posted January 17, 2016 Share Posted January 17, 2016 Looks like an issue with docker, specifically the dockercontainer.img It seems if you have a corrupt container this will pop up in your ssh session to the server. I had to blow out the old img and create a new one and re build all my docker containers. Quote Link to comment

I get this msg regularly and my dockers are working fine!!?? Quote Link to comment
hurricanehrndz Posted January 19, 2016 Share Posted January 19, 2016 I get this on my desktops as well. Its just a kernel message that is benign Quote Link to comment
PhAzE Posted March 25, 2016 Share Posted March 25, 2016 I'm getting this too, just recreated my docker this morning, still happening. In fact, some of the mappings on my docker are not working properly either while this happened to start showing up. Probably just a coincidence though. Quote Link to comment
MortenSchmidt Posted April 12, 2016 Share Posted April 12, 2016 I too get this, probably happened 3 or 4 times in total. Today happened on 6.1.9 while building a docker image I'm (trying to) develop. In my case, syslogd is the sender and I noticed my tmpfs (/var/log) is full. Next time you guys get this, check df -h Look for: Filesystem Size Used Avail Use% Mounted on tmpfs 128M 128M 0 100% /var/log In my case /var/log/docker.log.1 was about 127MB in size (of mostly jibberish). Last time this happened docker didn't like it a lot either - already running dockers worked fine but I was unable to start/stop new ones (docker deamon seems to crash - impossible to check syslog since that stops working too). Any good ideas how to prevent docker logs from balooning like they seem to do for me? Quote Link to comment
guyonphone Posted May 11, 2016 Share Posted May 11, 2016 I am getting this too on 6.1.9 root@Unraid:~# df -h Filesystem Size Used Avail Use% Mounted on tmpfs 128M 2.0M 127M 2% /var/log Quote Link to comment
mbc0 Posted May 25, 2016 Share Posted May 25, 2016 me too... quite annoying when in MC Quote Link to comment
pinion Posted June 5, 2016 Share Posted June 5, 2016 You can add me to the list. Been getting it awhile. 6.1.9.... annoying. WTF is being done? kernel:unregister_netdevice: waiting for lo to become free. Usage count Quote Link to comment

Aside from the annoyance it is completely harmless Sent from my LG-D852 using Tapatalk Quote Link to comment
