I am wondering if anyone has come across this sort of issue before (not necessarily on OVH CloudVPS).
We are running TeamSpeak on Ubuntu, this usually work well. However we started noticing some packet drop, then it got a bit worse and speech in TS was getting distorted, followed by everyone getting disconnected every couple of minutes.
Using SSH was just as patchy, making it unusable, so I turned to Manager for KVM access and saw some errors: "eth0: tx hang"
At this point I did a reboot of the VPS, and after if came back up everything is back to normal.
The VPS would have had roughly 1 months uptime.
With our previous VPS providers we would have many months uptime, in fact I don't recall needing to reboot even once (except for updates), let alone have issues with what I am assuming is between the OS (Ubuntu) and Virtualisation (VMware) layers.
I do not want this to become a recurring issue...
This is a snippet from syslog and kern.log:
Any help with this would be greatly appreciated!
