High Ram usage

[iconnor]

Options -> Logging
Check DEBUG
LOG_DEBUG_TARGET => _zmc
LOG_DEBUG_LEVLE => 4

Restart zoneminder.

Now /var/log/zm/zmc_m[monitor id].log will have the logs.

At 1.35.16, it took me 500MB for 1 camera, after the 1.5GB update. How to fix? Buffer reduced to 2
cameras just stand to record.

Oops. I presume they do some cleaning up. Was there when I grabbed it a while back.

Try this www.magic919.co.uk/zoneminder_1.35.16~2 ... _amd64.deb

can you update the link?

I've reinstated it. Please try now.

Possible? Yes.

You didn't say whether you are doing passthrough or encode. Encoding takes a ton of ram too (default settings will buffer 20 frames in the encoder).
Passthrough can buffer some stuff but it is encoded data and should just be ref counted so shouldn't amount to much.


--I'm using passthough. I tried to keep it as simple as possible... though sometimes it gets a little fickle. I left most of the settings close to default minus some tweaks from the upgrade (buffer from 20->2, logging, api settings etc)

I'm noticing that the memory issue is only happening when the cameras are set to record of any kind, and then drops back off when the event(s) are complete and the process starts over again (~10 mins) . I also noticed that there are 4 zmc processes per camera enabled. Could this also be attributing to the resource hogging? I have my install running with 24G of ram, 12G of swap and can literally watch the usage increase even though there is little to no change in the image being captured (an empty room in my house that gets no foot traffic -- ever). 10 rtsp cameras set to monitor == 4.5~5.5G RAM; change 1 to Mocord, system will again start hoarding memory.

Isaac, is there possibly a memory leak in the zmc process when in record mode?


Thanks,
