The world db log file and ldb files are getting to be bigger and bigger at every saving world, finally get a crash.
Usually each one ldb file in world's db folder that is 1MB - 2MB, right? But After update higher than  1.17.34, log file will be big until 2GB, and few ldb files are 17MB, then playing slowly, lag, can not open chest,  finally crash. 

But this case is on one of my world only. Other small world is OK.

And I tried down grade to 1.17.11 minecraft software. This is no problem.  

Actually, the world has a lot of entities. Chests and hoppers, trap, villagers etc, so certainly my world has problem, but lower version does not have problem, This is new version's problem I thought and reported. Is this already issued?

Regard.
