Crashes after a few days - memory leak?

[jfarre20]

Got this after a few days uptime, restarted the container and it did it again after a few days

Error would repeat and spam the console

This error has an open issue with OpenCV.js: opencv/opencv#19397

Though I'm not convinced it isn't something I've done. Are you able to check memory usage when it first starts, maybe a day later, and finally when the error crops up? Maybe there's a memory leak somewhere.

Maybe there's a memory leak somewhere.

there's very much a memory leak, it starts at around 4g used and after a day it's around 8g

I set the container to cap memory to 6.5 gigs, and this seems to restart the container once it goes over that

I have two 4K cameras H265, 15 fps. I'm not sure if the memory leak is coming from FFmpeg.

Can you post your (sanitized) config here? I'd like to try and replicate the issue.
