[NOAAPORT #MJB-944803]: rhel8 noaaport gaps

Sean,

Yes, and I went back through my RedHat ticket notes on that, and found how

If the O/S isn't dropping packets and the noaaportIngester(1) receive
buffer is large, then the only way you could see gaps is if the packets are
arriving faster than noaaportIngester(1) can process them.

Is the VM doing anything else?
