I am running Debian with 32GB memory and a six core, 12 thread, Ryzen. I have six threads and 16GB allocated for BOINC. The issue is that the process will stop doing any work according to 'top' for many hours even though 'boincmgr' shows it is running and not suspended. Sometimes restarting BOINC with systemd or rebooting gets it going again. I have my prefs set to always run both in the web prefs and local prefs. It seems to usually happen near the end of the work unit run with the elapsed time increasing but the estimated finish time not moving. Any ideas?
