The computer has Intel graphics only. I start mythbackend this way: mythbackend -v channel,idle,eit --nodblog --syslog none This is mostly a backend-only machine, the frontend is usually run on another computer. mythlogserver constantly eats CPU time in this setup. I used strace to see what it is doing, and it seems to be busy with poll() calls with timeout 0, so it immediately returns. It looks like this: [pid 4940] poll([{fd=28, events=POLLIN}], 1, 0) = 0 (Timeout) I tried to measure this, with the following result: {{{ $ ps aux | grep mythlogserver | grep -v grep mythtv 4938 0.5 0.1 613324 14772 ? Ssl Mar17 11:17 /usr/bin/mythlogserver --daemon --verbose general,channel,idle,eit --loglevel info --nodblog $ timeout 10 strace -ff -p 4938 2>&1 | grep ""poll.*, 0)"" 2>&1 > out $ wc -l out 2051 out }}} So there are more 2051 poll() invokations with zero timeout in 10 seconds, more than 200 per second. I also log console output, and the above also happens when nothing happens in console output. So mythlogserver is constantly busy even if there is nothing to log. I expect mythlogserver to be idle when there is nothing to log." Bug Report - General closed minor 0.27.3 MythTV - Mythlogserver 0.26-fixes medium fixed 0
