Signal 6 is the abort signal, which means that smbd killed itself due
to some unrecoverable error. If it's always smbd dying, check
/var/log/log.smbd and /var/log/messages for possible errors, and if you
can't find any, try running smbd on a vty (i.e. don't background it)
and see if it prints anything to stderr when it dies. You might have
found a bug in samba.
The icmp message is simply a side-effect of smbd dying. You can ignore
it.
