[tech] Molmol rebooted

[David Adam]

OpenVZ containers on Medico weren't working, the website kept dying 
because phpBB calls flock(), and many NFS things were unhappy.

This is because the NFS locking daemon (rpc.lockd) on Molmol hung in an 
uninterruptible sleep (D state), which is apparently a rare occurrence on 
FreeBSD fixable only by reboot. So I did - Molmol was bounced and came up 
nicely.

I was moderately impressed with how well pausing all the running VMs and 
then rebooting the NFS server worked. After unpausing them, they just kept 
running.
