[2.5] No logs stored in /var/log/maas/rsyslog/

Aside from the fact that there's no logging anymore in maas.log and /var/log/maas/rackd.log, I started seeing a lot of these on rackd.log

my wild guess, is that something with syslog is causing the increased memory consumption becuase there's no files written. Maybe they are all storage in memory which is causing the issue.
