I've been struggling to set up a system on a Raspberry PI 4 using a Hauppauge dualHD dongle. While it appears to work now as soon as a recording starts the web page fails to load and the log shows a loss of comms:

Trying to reconnect... Reconnected to Tvheadend Reconnected to Tvheadend Reconnected to Tvheadend Reconnected to Tvheadend

I've moved the dongle to a powered USB hub as I thought at first the extra current draw when the dongle starts streaming might be pulling down the bus and resetting it but this hasn't improved the issue.
I've also tried a complete reinstall with --purge but no luck on that.

If I try to stop and restart the service at the command list this is the status from systemctl:

`
arthur@pi-tv:~ $ sudo systemctl status tvheadend

The version is version 4.3-2155_gfe4df311d

I'd really appreciate advice on how to investigate further.
