Core files are created by the kernel when a process crashes. Unless you
already know which program crashed and why, it is probably worth
investigating.

As a first step you could just use the file utility to find out which
program crashed.

file core.*

should print something like

core.26166: ELF 64-bit LSB core file x86-64, version 1 (SYSV),
SVR4-style, from 'sleep 120', real uid: ... execfn: '/bin/sleep' ...

for each file. (Of course the program won't be "sleep" in your case.

To analyze the coredumps further you would have to use a debugger (e.g.
gdb).
