This is the issue, when im exploring with my friend, hte server just froze and brokes. i do have 12gb of ram for the server but still having this issue :C

hs_err_pid17924.log
hs_err_pid27940.log
hs_err_pid9844.log
This is the only "error" files i can find, they said insuficient RAM? but i have 12gb D: i cant put more i only have 16gb on my pc, hope someone can help me

Best I can say here is lowering the amount of RAM allocated as one of the possible solutions suggests. Likely, too much RAM has been allocated.

Closing because older versions are not supported and this appears to be a RAM problem
