Media worker accumulates over 1000 connections to mega.nz #15440
Description
Description
Our homeserver is accumulating connections to mega.nz (31.216.145.5) at a rate of approximately 2 per hour, most likely corresponding to URL preview requests for mega.nz. The largest amount I've seen is 1025 connections, spanning two media_worker instances.
Steps to reproduce
- Request a moderate amount of mega.nz url previews over a long period of time
- Observe the effect on the server via e.g.
netstat -an | grep 31.216.145.5
I am observing the same https connections being open from 10 hours ago, as well as additional new ones opening.
The URL preview requests complete as expected, but the https connections are never closed, and new ones are slowly added over time.
I would expect that at some point the connections would be closed, rather than being staying open indefinitely.
