Can you reboot the Hub and check the PostRS errors after a few hours, as they should be zero. If they keep rising you have an issue with your circuit and VM will need to fix this.

In the meantime setup a BQM to record and monitor your circuit   www.thinkbroadband.com/ping

I see the PostRS errors are coming back?  Just keep an eye on those as it really should remain at zero or a very small number. 

The BQM is a tad spikey but nothing to make VM take a look at the moment.
