FYI - the presence of a core file is not, by itself, evidence of a
serious problem.  We know that we have a small number of bugs that can
cause crashes (and so core files) during an otherwise normal process
shutdown.  They're mostly race conditions in how destructors are invoked
or other cleanup activities.  Because they only happen during shutdown,
they don't have any operational impact, and we've just never finished
hunting all of them down and working out fixes; they're slightly
annoying, but no worse than that.

So - if you can correlate the timestamp on a core file with an
operational problem, then it's a big deal and should be reported as
such.  There is a sipx-snapshot option that can be used from the command
line to include the additional data needed to interpret the core dump,
and it also helps of you've installed the -debug rpms (which,
incidentally, we should have a global target sipxecs-debug for).  

If the timestamp on the core files closely matches a deliberate restart
or shutdown (remember that changing dial plans and some other things
trigger restarts), and you are not experiencing some other visible
problem, then that core file is probably not worth worrying about.
