Andrew Bogott has uploaded a new change for review. ( https://gerrit.wikimedia.org/r/376057 )
Change subject: nova-conductor: limit number of workers ...................................................................... nova-conductor: limit number of workers Jaime writes "Is there something that could be done to reduce the amount of connections per service? every one precreates 40 or so, and among them they have constantly 400 open connections, in most cases always sleeping." There are 12 CPUs on labcontrol1001, so this should reduce our workers (and, hence, active connections) by a third.
