Major Server Issues

I use pixelmon 5.0.0 beta12 on a sponge 1.10.2 server. All is perfectly great until it automaticly closes very often. It starts to deterr players and it costs 50$ a month for the 10,240 MB! Ive been trying to find out for days what is wrong and no crash report show!

Here is the regular log i could get but idk if it can be of use.

[details=Summary][12:37:39] [Server thread/INFO]: Starting minecraft server version 1.10.2
[12:38:00] [Server thread/INFO]: Loading properties

[12:38:21] [Server thread/INFO]: Preparing spawn area: 27%
[12:38:22] [Server thread/INFO]: Preparing spawn area: 46%[/details]

And right after that last line, it just closes back! Please help!!!

Here you go, idk if it helps much but i can only hope.
