Hi all out there,
today it happened again - I've found out some strange behaviour in Proxmox 4 with LXC Containers. Container is running Ubuntu 14.04 LTS all updates applied, Node is running Proxmox, all patches applied:
Please have a look at uptime output and on performance metrices - they're quite different and container was not restartet.
I've no idea why this happens but it seems to be independent from which kernel is currently being used. I experience this already since long time but only found time now to document it here.
Thanks for help
Andreas
