Does anyone know why I keep seeing these messages in my debug.log file:

This is not an on-site network issue... it's unique to GSR.

When it happens the wallet spikes up to 99% CPU for a while, then after a few minutes it 'breaks free' and is ok again.
I have masked the last part of the IP addresses from the log.
