Forge server "Can't keep up!" in Support & Bug Reports Posted April 10, 2017 · Edited April 10, 2017 by LizNet 4 hours ago, Matryoshika said: The network I'm part of, makes use of TickProfiler, a Forge mod that lists resource-hogging Tile-Entities and Entities, per time/tick average, per tps%¹ they are draining, per chunk² and per type³ ¹Take this with a bit of salt. If something states it is causing 50% of the drain, it may very well be a big drain, but the profile cannot see everything, yet tries to stretch what it can see to how much is drained. ²allows you to see the chunks with highest activity, most of the time player-bases centered in a single chunk, for example ³Shows the tile-entities and entities that collectively stand for the most drain. Take this with a bit of salt as well, as it does not take into account -how many- of said type there are. While this may not solve your issue, it should enable you to find the largest TPS-drains on your server. Tried th TickProfiler, then removed Forge Essentials and I have saw none of thse warnings anymore. So it was caused by Forge Essentials, don't know why it used so much resources that the server was unplayable. But thanks to you (and TickProfiler) I managed to solve this! Now I can even use Sponge at the same time.
