We are running 9 mods on Ragnarok and have placed atleast 100 spawners around the map adding all the resource and dinos from all the other maps.
We have went through all the other mods and Simple Spawners seems to be the one causing it. We remove SS and the crashing stops and when we try to load the back up the server crashes right away. We have completely deleted and redownloaded the mod several times, and also tried the reset command, dino wipes, ect..
This is the crashstack we have been getting.

Any insight as to what might be causing it would be greatly appreciated.

The version number is old on that crashstack the server is always kept up to date.
