High memory use

Edwin de Graaf

I have been using Tvheadend for a week now, and I feel it is using a lot of memory.

egraaf@tvheadend:~$ ps auxww| grep tvh

hts 950 0.0 1.3 916612 27244 ? Ssl 17:08 0:06 tvheadend -f -u hts -g video

I use the testing repository (4.0.6-9~ga1170f9)

The DVB-C interface is HDhomerun, there is no encryption on the coax.

Yesterday the Tvheadend process was killed because the 1GB memory I assigned this VM was full. I have now given it 2GB, but this seems excessive.

Otherwise I am really happy with Tvheadend, and I feel the 4.06 release does better at detecting my muxes than 4.05. With 4.05 I used to have some muxes in FAIL state, and now they all show OK.

Please let me know if there is a way to reduce memory usage, or how we can find out why it uses so much.

If you're doing transcoding then that is your answer, Tvheadend uses ffmpeg code & it has some memory leaks.

I don't do any transcoding & mine stays at about 115mb usage with 6 tuners.

I use HTSP with the default profile to Kodi Tvheadend client, so I don't think I use transcoding. The DVR profile is set to "pass"

in that case please open a ticket along with valgrind output.

Run (as a superuser).

valgrind --leak-check=full --show-reachable=yes /usr/bin/tvheadend -c /home/hts/.hts/tvheadend.

Try not to make any changes while you're running Tvheadend under valgrind as a superuser as this may cause permission issues when running normally, you may want to make a backup of your config.

I ran it overnight from valgrind, but there was no output. So I don't suppose there is much point creating a ticket.

It just shows an initial message from valgrind, and then the regular Tvheadend output:

root@tvheadend:~# valgrind --leak-check=full --show-reachable=yes /usr/bin/tvheadend -c /home/hts/.hts/tvheadend [11/1982]
