<DIV><FONT face=Arial size=2>Found this message in pdns error logs on our two
pdns servers after noticing that pdns had done a restart - it seems to
happen every day at the same time almost exactly an hour after we finish nessus
scans and the resulting messages are exactly the same on both boxes. Can't say
that the nessus scans are causing it as it seems that the restart happens an
hour later after nessus has finished but there are no crons or scripts
running at the time of the signal 6 and it isn't restarting at any other time.
