I agree, this is a Dynamic C Bug, this is a Digi issue, and needs to be add=
ressed by Digi for all versions of Dynamic C that are required to develop c=
urrently shipping RabbitCore modules.
Open connections should be excluded =
from aging in the ARP table.

Subject: Re: [rabbit-semi] ARP Table size
Instead=
of making the table larger I would see about getting this bug fixed. An op=
en connection should be excluded from aging the entry in the ARP table.
