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.
