Tvheadend

What do you mean with 'memory' in this case? 'ps' or 'free' ?

I use 'free -m' to see the usage, memory is decreasing and caching is increasing.

Also circumstances that may have had an impact, I ran 'sudo apt-get upgrade' before installing some other software today. I can't imagine that this happened during my recordings in the last week, as my system (RPi) would've crashed.

I did some more testing, and the same occurs in 4.0.9 and 4.0.9-17, so I reckon caching isn't working properly as result of an upgraded package or something of the sort. Perhaps it never worked, I can't tell to be honest. For some reason recordings are being cached till it reaches the last 25 mb of memory, at the point the total usage is 430 MB, and then it's just fluctating. So the whole 'cache scheme' setting doesn't appear to be working.

Is the memory usage causing some problem? If it is just cache, it should be freed if something else needs memory.

You can try to run "top" and see if it is the system or tvheadend using the memory.

It appears my lack of knowledge of Linux got the better of me. Thanks for the help, it appears my system just starts caching recordings and the like immediately, but this cache/buffer is still considered free memory.

This issue can be closed.
