100% cpu usage on 1 core

Added by Anders Falk over 10 years ago

Hi

My clients drops connection towards the Tvheadend server occationally. Running top shows that the tvheadend process is running 100% on 1 core. Webgui is also down during these times. Got a tip to do debugging but not to familiar with Linux I'm afraid. I see there is a debugging setting in the gui. Will this be enough to gain some information? Now running 3.9.570 but it has been like this since 3.9.

Is this a known problem? Feels like something is running on an hourly basis or close to.

Not been able to debug...but found this running dmesg.

[ 8686.145433] traps: mpegts_input_ta1967 general protection ip:4133dc sp:7f8108ff7ff0 error:0 in tvheadend[400000+d0000]
[ 8687.363831] init: tvheadend main process (1243) killed by SEGV signal
[ 8687.363896] init: tvheadend main process ended, respawning

Could this be interrupt related? Running TBS6985 with MSI interrupts according to this:

Not shure if this applies to Ubuntu 14.04...other syntax?
