[RadiusNT] SNMP concurrency-checking inconsistencies

On this past sunday, two of our Max 4048s reset themselves (don't know why
yet) and as a result, the users who were online could no longer log in
because Emerald (2.5.278) / RadiusNT (2.5.175) thought they were still
online (there were 247 "over login limit" errors before I realized that
they reset). I set up the SNMP concurrency checking several weeks ago and
thought that things were running smoothly, but apparently it's not
functioning correctly and/or consistently.

Below are two login attempts for a test account (dialup via modem) with a
login limit of 1. The first one (and several previous attempts) failed
because of "over login limit". The second one displayed below apparently
authenticated successfully, although nothing had changed in the
configuration for the account, RadiusNT, or the Max. In the RadLogs, the
Description, "SNMP Check Failed" showed up though. The RadiusNT loading
options are at the end.
