I am trying to leave a RTMP stream converting to HLS up for over 24 hours but I am running out of heap memory. Is there a limit on how long of a live stream is supported? Is it a typical use case to leave a live stream up indefinitely? I have looked at the docs on heap memory and such, but my question is what is the max length of time for a live stream?

This must be something with your stream, with the setup of your server or with any optional custom plug-ins. Theoretically you should be able to run RTMP -\> HLS live streams indefinitely; there’s no reason why it should crash because of Heap Size issues.

- Do you have a server with reasonable specs and have you set the Performance Tuner to Production (default after installation is Development Mode if I remember correctly)?
- Have you made any custom changes to the server or Application (e.g. HLS chunk size, playlist size, etc.)?
- Are you using any 3rd party plug-ins or modules?

I confirm.  
We keep several dozen streams running 24 hours a day - no problems.  
We use custom modules.  
Hardware and configuration - check it.
