I'v a 5 node cluster of proxmox 4.4.

I've setup a backup task that do some daily backup of some VM. The
backup task use a storage that is phisically on one of the server,
mounted to all other server via NFS.

In the server where the task actually have the NFS share, the task run
without trouble.

In all the other 4 servers, stalls:

I've tried to restart nfs-common in a client, and nfs-kernel-server in
the server but seems does not change.

Processes are unkillable, even with 'kill -9'.
