Why not? At least you can tell if the high cpu usage is caused by the
scanning process. Make some changes in the LMS settings and continu the
scanning ?

Re: [SlimDevices: SqueezeCenter] LSM 7.9.1 Nightly on RPi3--LMS server unresponsive to connections
I did not "know" about the full text search until I did some more digging. I may do that. I also learned about cgroups as part of my research. cpulimit is really for already running processes, which is why I tried using that. I didn't want to kill the library scan by restarting LMS.

Try disabling the full text search plugin.

https://www.tecmint.com/limit-cpu-usage-of-a-process-in-linux-with-cpulimit-tool/ Can be used to modify CPU usage of a *running* process. Can only be used from a terminal session. Is not permanent. But if you encounter a situation like mine where LMS is basically useless, you can affect how LSM and the scanner process use CPU, memory (using ulimit) and priority (using renice). I may never using the LMS web ui Scan/Recan options again and just run scanning from a terminal session so I can use these tools. gstalnaker's Profile: http://forums.slimdevices.com/member.php?userid=63504 View this thread: http://forums.slimdevices.com/showthread.php?t=108720 ___ Squeezecenter mailing list Squeezecenter@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/squeezecenter
Re: [SlimDevices: SqueezeCenter] LSM 7.9.1 Nightly on RPi3--LMS server unresponsive to connections
While renice does modify the priority it does not modify CPU use. And though I was able to connect to the LMS web UI after its CPU use fell, the minute I clicked on anything in the UI to "show" content, its CPU shot back up to 100% and now I cannot connect again. So it's not just priority. On a RPi3 running the latest Raspbian and the latest LMS nightly with Perl 5.24.x etc. The scanning "build index" process effectively renders LSM unusable. Back to my original question -- how can this be fixed? Or can it? gstalnaker's Profile: http://forums.slimdevices.com/member.php?userid=63504 View this thread: http://forums.slimdevices.com/showthread.php?t=108720 ___ Squeezecenter mailing list Squeezecenter@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/squeezecenter

One can use at the CLI: #> ps -ef | grep squee to see list of the processes that include "squee" which will show the primary LMS processes and the Scanning process if running. Note the Proccess ID (PID) of the scanning process. In my output from earlier: squeeze+ *1480* 396 34 00:16 ? 00:29:53 /usr/bin/perl /usr/sbin/squeezeboxserver-scanner --logconfig=/var/lib/squeezeboxserver/prefs/log.conf --logdir=/var/log/squeezeboxserver/ --priority=0 --novideo --noimage --prefsdir=/var/lib/squeezeboxserver/prefs --wipe --debug scan=ERROR,database.info=ERROR,scan.auto=DEBUG,art work=ERROR,scan.import=ERROR,scan.scanner=ERROR Renice uses this format: #> renice -p Default niceness value is 0, 1-19 is REMOVING priority. -1 to -20 is INCREASING process priority.
