	Maybe the problem was a previous problematic restart. In our
installation, nagios (nagios3, but previously nagios 1) is working
smoothly. We don't have any problem like you, but sometimes when we
restart it to reload configuration (if we have added hosts or services).
Sometimes, the restart fails and we have several instances of nagios
running and appears a similar problem. Killing all nagios processes and
starting again fix the problem.

	We configure nagios with centreon and we don't know if this a
problem
related with centreon or with a startup scripts (centreon uses them).

	But, if we don't reload nagios, it runs without problems.
