Default arp command failing

Hi everyone,

I'm having periodic problems with the arp command returning -1. I've been unable to determine the conditions that cause this, or even any info on what could cause arp to fail.

I'm calling % arp -an through the PHP functions shell_exec() and exec() - both of which are simply intended to run a shell command.

Like I said - this is periodic. I can have this error generated multiple times 1 minute, then have the same code run 5 minutes later with no problems.

I'm not sure if I should be looking at the server load for the culprit, or maybe network load?

Thanks for any & all help.

P.S: Running on a 4.7 box upgraded from 4.6.
