I am forwarding my replies to the Nagios list as well.

You can determine that you are running ndoutils by issuing a command like "ps -fu naguos" (to list all processes owned by username nagios; if you are running ndoutils, there will be a process named ndo2db

In our case, the process causing the main problem was running on another server, but was holding up nagios because it blocked the nagios process in part of the code that was single-threaded.

Can he be contacted for his advice ?  If not, what has been changed since you took over (probably asking the obvious questions !)

1MB sounds very large; if you see it again, try finding out which check generated this file (core or debug dump from check code ?).
