Crash every 30 mins "sometimes even earlier"

Crash every 30 mins, and i have to close the realm before backing it up. if i dont do so the backup will fail. note: i have 2000 members on my realm and people dont even want to build anything becasue they say its not worth there time because i always have to back up the server 5 hours before the crash{sometimes even more}. once i get the realm back up 9/10 times, the world is comepletly reset or has like 32767 chunk errors. (alot of chunk errors) i hate having to come home with 32767 messages saying FIX THE REALM FIX THE REALM!!! do something about this please PLEASE. no one wants to pay for a realm that barley works

i also like how you said you fixed the crashes...
