MEDIA ENCODER STOPPED RENDERING!! PLEASE HELP!!

This is what I was able to get to work for me. Your mileage may vary. When my Media Encoder would stop rendering I would click the "pause" button to pause the rendering operation that had stopped anyway. Press Ctrl-Alt-Del to bring up Task Manager. Under "Background Processes" you'll see Adobe After Effects. Click on it and then click "End task". AE will come right back up but it will be at much lower memory use. Un-pause your render job in ME and after a few seconds it should start going again. This happens when total memory in my system gets around 75% used and AE is using 15gb of that. There's more than enough memory to spare and I don't know why ME decides to quit when AE gets that high but it did. You do have to babysit your render job to repeat this proces but it worked on my end /shrug

Same here. It'll render a few clips in queue, but the whole application crashes after an hour or so. 

I'm having the same problem. I think it might have to do with encoder because I was able to render 3-30min videos at anytime, until I updated. Now I can barely render a 2minute video but have have to change settings to 720p

Would you check the load balance of CPU and memory to find the cause? You open Task Manager app for Windows and Activity Monitor for Mac. If the task is too heavy for your PC, you need to improve your hardware spec.
