One core maxing out then server freezes indefinitely

[BiZR 1]

Ever since switching to Esseker I keep getting these weird freezes where the server will just stop working and everything is froze in place. I use DMS, Occupation (with occupyPlaces disabled, mainly used for traders and transport) and ExileZ 2 with a low amount of zombies unless a horde spawns which is set to 20. Doesn't seem to be anything in particular that causes the freeze and the RPT logs stop writing during this time but querying the server through A3Launcher works perfectly fine still so it hasn't crashed, just froze.

Seems to happen when people uses traders, I use the easy trader setup by red_ned and have NIA, CUP and EBM enabled from it, nothing else.

Every time it freezes one of the cores is just maxed out, doesn't matter if there is no zombies, etc spawned in or 1 player or 10. When it freezes server just goes 100% full on one core.
