NGINX+RTMP periodically crashes, maybe something is wrong in the config?

Question

linux

NGINX with the RTMP module freezes periodically, the video stream is still being sent to the server, but the statistics and the player are empty, only manually restarting NGINX helps.
I can’t understand what the problem might be, a similar config on the NGINX Windows assembly works stably.
Debian 8 is currently running on the server.
