one world (local)  I've been working on for a couple of years suddenly started consuming 100% of my 32GB ram plus huge amounts of swap space. The world will eventually finish loading after a few hours but performance is extremely poor and memory remains spiked at 100% with high swap usage. I restored the world from a backup and it worked ok for a day or so and then the same problem manifested again. All of my other worlds load and perform just fine. It doesn't crash so there's no crash log and the .log file in the world directory is empty.
