I am trying to troubleshoot a message that floods dmesg:
[Tue Mar 5 20:46:23 2019] traps: g16[7254] trap invalid opcode ip:404956 sp:7fff6d7c6200 error:0 in g16[400000+4cf7000]

This is linux:
bash-4.2$ uname -a
Linux cx1-138-5-1 3.10.0-957.5.1.el7.x86_64 #1 SMP Fri Feb 1 14:54:57 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
This happens continuously, at some interval. Is there any way to identify which program it may be, eg. from the ip:404956 which seems to always be the same?
The process is clearly showed in that output (g16 with pid 7254 etc). The ip and sp are the instruction pointer and stack pointer registers.
Error 0 if you look here: is the divide by 0 error.
