Probably caused after punching ejector while tron metadata was spread all around to incorrect nodes. Or after trying if duplicator could get layout out of broken tron.

Upstream issues:

• Seems the inventory table is not retrieved minetest-mods/digtron#40
• Potential Lua memory allocation problem when system memory is running low minetest/minetest#8067

Crash should be mitigated (the actual cause not so much)
Closing the issue on this end...
