Default message at logs: kernel BUG at mm/rmap.c

Guys, any idea besides memory problems that can cause this? I already
double checked memory with memtest and didn't find any problem. I also
checked for heat, but the machine is in a datacenter very, very cold.

Could be an electrical problem?

Thanks for any thought you have!
