You probably have a memory leak, e.g. not closing opened resources, like files — Lino, Feb 12 '19 at 14:01
The graph in the second picture shows that it only has 300mb of heap tho. Double check if it actually is using your config or it overwrites it. — Wesley De Keirsmaeker, Feb 12 '19 at 14:11
@WesleyDeKeirsmaeker, It shows Xmx:1024 in its JVM Arguments. — Cody at N-developer, Feb 13 '19 at 05:22

-XX:NewRatio=2 means that:

old generation size : young generation size = 2:1

So the young generation size is 1024/3 = 341M. It means that:

Eden size + 2*Survivor = 341M

The Eden size is about 300M.

You should set Xmx bigger.
