Try to remove this from disk in order to drop the waiting 5k items being 
put on the socket.

Having a fresh startup of nagios and ndoutils, the config waits to be 
written, before some more realtime/config cleanups and after that, the 
historical cleanups leading from ndo2db.cfg might also interfere the 
normal insert/update procedure. this is when the socket gets blocking 
and ndomod is buffed with data it can't even send to the socket.

Regarding 1.4b7 - consider getting the latest cvs head and patch the 
unique constraint bugfix on nagios-devel yourself onto mysql.sql

It's not "the latest and greatest" ndoutils, just "the latest" though.

Kind regards,
Michael
