iMac Late 2013
Quad-core Intel Core i5
Ubuntu 21.04, ufw firewall disabled
Roon Server: 1.8 build 814
Roon Endpoint: ios app 1.8.00814
Netgear Nighthawk router, unifi ac lite AP
iPhone 6s running roon connected via wifi and outputting through dock connector
Three times in the last 10 days my Roon core has become unresponsive. On the host I find an unusually high load average and CPU utilization. Restoring Roon core services can be done with
sudo systemctl stop roonserver and then restarting it. This also releases the utilized CPUs and drops the load average. The second time this happened I let it run overnight, but still had to restart Roon core in the morning.
htop shows 6+ processes calling RoonAppliance --debug
How can I stop this from happening so that Roon will run in a stable way not requiring restarts every few days?
