Did you have an idea why i hate this problem ? Thanks a lot

This bit - MaxImageBufferCount:5

Up it.

[TheRoth]

It's worse ! And if MaxImageBufferCount is 0 (unlimited)
I have "Restarting capture demon" every 10 seconds and all video is broken...

Thanks

[TheRoth]

Maybe the problem is here ?

ipcs -l

[Magic919]

It might just be broken.

[TheRoth]

Thanks Magic919 ^^

It's already a new fresh clean install...
What is broken ? RAM ? ZoneMinder ?

[Magic919]

This is a development version of ZM.

[dougmccrary]

Did you have an idea why i hate this problem ?

Because it’s taking up too much time?
You probably would be happier with 1.36.10,
Either the release or proposed. They work for me out of the box on Ubuntu.

[TheRoth]

Sorry for the revealing slip, english is not my native language ^^

New test... It's work very well with 5 camera IP... if i turn on 6 cameras..., the problem appears...
Do you think this could be a network problem?
i'm sure i will find an solution ^^

[TheRoth]

So, i downgrade to v1.36.10 for bullseye... and same problem.

[TheRoth]

Maybe you will find an error on this ?

Can you lower the frame rate in the camera? Like it said earlier - analysis can't keep up.
Try 5 or 6 fps on the cams.

[TheRoth]

Thanks Doug,
It's Work well with 8 cam IP
But... 5 FPS that's not really good ! What did you think? Bug ZoneMinder? Problem Hardware, Problem Network ? System Problem ?

[TheRoth]

If you want more information...
This configuration work. Load 5 % ... But CPU 50-60% on top -i

Load 5 % ... But CPU 50-60% on top -i

Load isn't a simple percentage

Roughly speaking, a load of 1.0 means one CPU core/thread at 100%, so if the load is greater than the number of CPU cores (or threads) then the CPU may be overloaded.

nmon is useful and gives much more information that top: http://nmon.sourceforge.net/pmwiki.php - You can probably install it using your normal package manager (apt/yum/etc.).
