As an aside ...

The thought of putting recovery state/log files (i.e. the DHCP leases 
file and its backup) on a RAM disk to make top look pretty leaves me 
dismayed. That leaves zero local protection against a system crash (or 
misguided deliberate reboot).

And yes, the server has been running 346 days -- Doesn't matter. 
Services can be five nines reliable, but hardware won't be.

An SSD, or if you prefer multiple SSD units configured as a raid, will 
give you the same order of performance without the premortem fodder.

The machine should be audited for other critical files which are written 
to volatile storage, and moved to the SSD or other storage as well.
