LXC - NFS - neighbor table overflow

[latelier]

Hi,

We have a Proxmox 4.2 and testing lxc nfs integration before switching to a bigger server and buying the proxmox support.

It was working fine at first but I'm getting glitches now, they lose their mounts.
I rebooted the host station in hope of fixing any issues and here's what was written in the log (see attachment).
On boot all container's NFS mounts we're down.
Restarting 1 container at a time fixed the mounts...

I recently migrated some openvz to lxc, I don't know if that could of caused anything to go wrong.

You may want to look in to https://forum.proxmox.com/threads/lxc-nfs.23763/ , keep in mind your security requirements when you change the lxc-default-with-mounting , as you will be change the allowed mount types for all LXC containers on the host.

For the nat error you may need to up net.ipv4.neigh.default.gc_thresh* in /etc/sysctl.conf, http://www.cyberciti.biz/faq/centos-redhat-debian-linux-neighbor-table-overflow/

I made the modifications in "/etc/sysctl.conf" we'll see how it goes.
Thank you very much
