Signal 11 happening "out of no where" on machines which have been
running fine, most of the time, is a sign of hardware failure (usually
RAM, but sometimes motherboard or PSU).  The fact you got a reboot is
also further evidence of this.


I would recommend taking the machine offline and running something like
memtest86+ on it for 6-7 hours.  Any errors seen are a pretty good sign
that you should replace the memory or the motherboard.  You can
download an ISO or floppy disk images here:


Bottom line is that this is probably a hardware issue.
