Memory: 83383216 bytes (79 MB) / 2110783488 bytes (2013 MB) up to 2110783488 bytes (2013 MB)
Server ran out of memory (that may be a different problem that the current 1.13 snapshots/prereleases are allocating too much memory)

So 2 GBs are not enough for 5 players ? What is the recommended memory allocation ? Should I try with 4 GBs ?


Got it, so for the time being, I will just restart the server from time to time. Thanks.
