Server freezes
KostromDan opened this issue ยท 8 comments
M-Tech modpack 1.7.0
Install canary(I've temprorary removed it)
Create world with seed -3531681273743420041, fly in this direction, randomly locating biomes with nature compass, after some time server will completely freeze.
Crash will happen even without this actions, but I'm saying that I've done.
If we rejoin world, already crashed it will crash again less 1 minute.
Removing Canary fixes problem.
Removing Smooth Chunks with enabled canary doesn't fix problem,.

for me reason is:

For my modpack reproduction is:
- seed: -3531681273743420041
- /tp 100 150 -5300
- freeze
Initially thought that Canary causes this, but it only increased chance of this problem.
additionally, i can now say that the crash often occurs when a player joins the server. after this happens the server runs just fine

We have different reasons.
