problems of ffield.reax.lg

Dear all.

When I use ffield.reax.lg to anlyse mechanical properties , there are always some errors which I never met before. I don’t know the which aspect is wrong and what the errors mean and how to solve it.
Attached is my in file and error file .

It seems that it’s a hardware problem. When i use the machine and ffield.reax.lg to simulate carbon-based material, I
can get the computing result with no error.But when i analyse material of Si with ffield.reax.lg ,there‘re always error like that.
So it looks like there’re no problem of machine&hardware.
So what’s the problem?
