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). hp -- _ | Peter J.
