Large File Downloads Fail At Random States of Completition

[randominternetuser]

In an almost identical situation to #2911 according to the trace logs the FileRelay will randomly disconnect without error sometimes 7MB into the file, sometimes hundreds of MBs into a file. It does not seem to be effected by WebRTC or not, local network or via a reverse proxy.

Steps to reproduce the behavior:

1. Open file manager and download any decently sized file.

I had this issue previously. I chased it forever with no real resolution.

I ended up upgrading (via re-install and backup/restore config) my MC server (same cloud provider) to one with more resources and it went away. My performance issues with client devices also went away. I initially did not think the host was the issue because top never showed more than 50% cpu or memory utilization for the prior server.

Add more resources to MC and it went away

How many more? You provided no context. If you had 1 core and 2 gigs of Ram, I get it. What if you have 12 cores and 64GB of RAM? I have this issue, but your comment doesn't tell me how much I should increase.
