What size have you set your buffers to, and how busy is your machine when you get alarms?

image size 640x480 b/w.
max framerate - 4 fps
buffers and other monitor parameters sets by default.
i am using 2 video in.

Yesterday there was an abnormal load average = 6, though it is usual under the same conditions no more than 2 - 3.

As lags of system have started to appear, in logs anything especially informative is not present, though on the console contents of a stack of process zma are thrown out

The problem was solved.
It has been connected by that the size of a zone left abroad images (I has changed the size from the big picture on small and the size of a zone has remained from the big picture).

I am aware that this is probably an issue that needs a little more work. If you define your zones as percentage sizes rather than pixel sizes you can avoid this problem however you will sometimes loose a little accuracy as piels values are rounded.

At percentage definition of zones at me not so high percent of detecting of movement. At pixel definition - result good enough!
