RTSPtoWeb - Running out out RAM and crash

[Joern-HAP]

RTSPtoWeb is running fine but after few hours, the RAM goes to 0 and PI is crashing completely.

Checking via SSH, I see with free -h, that free RAM with 991 MB at start - is going done to 40 and then crash somewhen...
Is there anyhow a way to free RAM or keep free?

After 2h:
