I was looking at my modpack logs and saw this "Memory connection overburdened; after processing 2500 packets, we still have 1668 to go!" I'm curious to what it means.
Means your CPU is struggling.
You could go through each mod and deactivate them. Pain in the ass though. Look for updates or a better CPU might help.
i usually see this when i have the game paused for a while. you could try increasing how much ram is used by minecraft but sometimes its just there. if you can still play and it only happens occasionally, i wouldn't worry about it.
