</div>When total channels exceeds 400ish (~65% inbound, ~35% outbound), system<br>
load suddenly spikes (under 350 or so, it's usually under 2 or 3, when<br>
we hit 400+, it will jump as high as 80). At that point the system<br>
appears to be queueing calls as the volume will sometimes shoot up to as<br>
high as 900, even though that's not really possible (hard limit due to<br>
T1 count), so it seems that it might be blocking on some resource.<br>
<br>
Also caught this error:<br>

<br>
So I adjusted that upwards as well.<br>
