<p>Hello,</p>
<p>enable latency logging and then you should discover if some
action inside kamailio takes longer or if it is something with
underneath layers. See related parameters in the core:</p>

<div dir="ltr">Interesting points. In this case though. here is
why I don't think its an AWS network limit:
<div>1)This instance was in staging and had almost no traffic at
that time. Why would a PPS limit have been hit? </div>

</div>
<div>2) The capture is taken directly on the kamailio box. If a
network limit were reached the packet would be delayed across
"the wire" which would only be visible in a capture on the far
side. Here we see the delay locally on the box. </div>

rule of thumb is that AWS has undisclosed and semi-disclosed
(and rather low) network iop and PPS limits EVERYWHERE,
including on instances whose specs are otherwise sufficient
for the job. If in doubt, try a bigger instance. <br>
