Hi ..my server crashed .. 2 days after wipe with 50 players online (pop average in day time  90-100) Entity Count: 80,867

This is the error:

Caught fatal signal - signo:11 code:1 errno:0 addr:0x7fffbe5dcfe8

I also noticed a drop of fps from 90 to 45 near this farm/base .Very strange a fps drop on a vanilla server .

The SIGSEGV signal is sent to a process when it makes an invalid virtual memory reference, or segmentation fault, i.e. when it performs a segmentation violation. Well this basically means that this is a Unity or Rust issue most likely.
