Bug Description
256 server MAAS environment on hardware.
rsyslog on bootstrap node starts to drop connections due to concurrency:
May 11 17:08:03 sm15k-1-03 rsyslogd-2079: too many tcp sessions - dropping incoming request [try http://
This is probably a ulimit hit in rsyslog configuration.

This sounds like there needs to a tweak to the rsyslogd process limits to allow more open file handles and/or a change to the maximum number of connections in rsyslogd's config.
