Are you seeing the start-up messages from dccifd?  If not, perhaps
dccifd is complaining in which log those are being sent.

Is the DCC home directory writable by the user running dccifd?
If you try to force a core dump with something like `kill -10` or
`kill -3`, does a core file appear?

Are you using the new DNS blacklist mechanism?

Does addin "-Bset_debug -Bset_debug -Bset_debug -ddd"
to DCCIFD_ARGS /var/dcc/dcc_conf produce any interesting messages?

Without some clue about what is happening, it will be difficult to fix.
