Memory usage on raspberry

Post by denvid »

Hi, I´m running a setup with two cameras on a Raspberry 3 with raspbian stretch.

First camera is a ELRO c800 with just one stream 640*480.

Second camera is a HiWatch DS-I430 using RTSP with two posible resolutions:
Main Stream 2688*1520
Sub Stream 640*360

If I´m running the second camera with the sub stream everything is working well.
On top right side on ZoneMinder backend I can see: /dev/shm: 17%

If I change second camera to it´s main stream I´ve got /dev/shm: 100% and I can´t see any video stream.

There is an externam USB drive attached to the Raspberry. Is there a solution to change /dev/shm to an external drive so that it is not running out of memory?

In advance thanx for any help.

tmpfs is RAM. Check out Debian forums to see if they can answer your question. Not a Zoneminder fix.
