Memory leak, checked with valgrind

lamko

I got a serious problem with tvheadend it's using 750 MB ram. Yeah I know Linux is using it for caching and buffers.
But if I start a movie with kodi the whole system locks up and I can't believe that memory needs to still be in use.
It should give it back to the system after sometime.
A simple reboot fixes all these problems but thats not where I'm after.
So I made a log with valgrind and in about one hour it's not giving back any memory. It keeps about 10 MB this not sounds like a lot but if you want your be Pi to be always on then after about couple of days it's running in at a Gigabyte.
I'm running a Pi4 with 2 Gigs of ram, Raspberry Pi OS 64 Bit with Debian Bullseye I also use the latest Tvheadend 4.3-2351~g078a822cf~bullseye with the debug installed.
I've configured valgrind with the suppression list from github.
The log from valgrind can be found here :

For more info just ask, I like tvheadend really much !

There isn't really a memory leak, the only thing that is leaked is about 10 MB of memory, but I am not yet sure where/how. That is likely not at all related to what you are seeing.

You can check in the Web UI (Debugging section, Memory information) what exactly is using how much memory.

Tvheadend is going from 25 MB to 75 MB already :
75.6523 MB 1751 /usr/bin/tvheadend
It's growing fast : after 3 hours was at 30 and in 1 hour to 75 MB !

Do I need to make another valgrind log when more time has past then 1 hour. If I do it for a day I'm sure I get a greater leak.
I watched Memory information but I don't see what is using al that memory it's all looking good.
