How many ZMC instances?

[rockandroller]

Doing testing and configuration... for the first time left the Zm running all night.
Seems to be working fine, but I notice there seem to be more processes now (or maybe I just didn't notice them earlier?)

I see one ZMA process per camera, but what appears to be at least NINE zmc processes per camera. Is this normal?

Also, what I would call "idle" server load seems to have doubled since yesterday, it's now running at about 1/4 of machine capacity, whereas yesterday it was about 1/8th..

this does look odd and I don't believe is normal. multiple instances of zmc should be transient (if at all) - not long lasting.
You might want to post more details about your config and zm debug logs and some knowledgeable folks may chime in.

Hi,

I saw this long time ago, but I read a post of an user explaining that ffmpeg sources usually uses more than one process. I do not know if it´s true, but in my zm server, the zmc process are also repeated in all the monitors using ffmpeg.

If you use ps instead of htop, you will likely see just one zmc process per camera, at least if everything is working correctly.

Unlike ps, htop shows each thread separately.

Thanks! Multi-threaded process totally makes sense

I think pressing "shift h" will hide the threads in htop.

Yes sir!
