Following up. A thousand thanks goes to Rugby (Daniel Beyer). It appears that his suggestion resolved the issues with my vanilla roon server installation (via easy install script). After removing the orbit folder, memory utilization has returned to a more normal state, and the crashing has stopped (for more than 10 tracks now! yippee!!!)
Here is memory over the last day. The cliff is when I applied the orbit fix.
Recommendation for @support , acknowledging your subscribers and setting my expectation will greatly increase satisfaction and temper frustration…
Thanks again Rugby!
