My users just reported that my bot was offline in some servers. The bot is in 2800 servers and had been up for about 8 days before this happened. I checked the RAM on the server but it seemed fine as seen in the image below. Unfortunately I couldn't get any error logs.
I'm mostly curious about the cases where this might happen so I can try to prevent it in the future. Could it be a RAM issue? DJS bug? Login rate limit? Something else?
