ZM stopped with error

[Thomas007]

My ZM installation has a bad tendency to stop by itself, once in a while. Today it did it again, apparantly caused by some network frame issue. Why are the incomplete frames not just discarded? I see this in the log, any ideas?:

Are you using UDP or TCP with your monitor settings? You should use TCP. Check the camera settings and lower the key frame interval and frame rate (5 FPS is good for security cameras). Check the tmpfs to be sure you are not out of space.

[Thomas007]

I don't seem to have a TCP/UDP options choice in the cameras, and no key frame settings.
One of the complaining cameras, a Trendet TV-IP320PI, has a main stream of type H264. It also has a secondary stream of much lower resolution, thus of no interest to me.

ZM receives data from this camera suing RTSP -> RTSP/Unicast. I guess that's TCP.

tmpfs is at 26% so it shouldn't be an issue.

[bbunge]

TCP/UDP is in Zoneminder - Source Tab - Remote Method

Key Frame Interval is in the camera settings and sets how often a full image is sent from the camera. Likely you should be using ffmpeg in Zoneminder.

[Thomas007]

Aaah. So, what equals what - is "RTP/Unicast" TCP?

Since my first post, I reinstalleded ZM on another machine. It lowered the /dev/shm usage, to the 26% mentioned, but now this new installation has stopped too. Like with my first installation, it seems to be caused by decoding frame issues:

ZM has stopped again. I can't say it's running smoothly. The newest part of the log says:
