i change the setting to TRACE for controller .
i have many messages :

rate limiting for agent XXXXXX

doyou think this is the issue

$ juju controller-config -c  juju-dev agent-ratelimit-rate
ERROR key "agent-ratelimit-rate" not found in "okc-juju-dev" controller
$ juju controller-config -c  juju-dev agent-ratelimit-max
ERROR key "agent-ratelimit-max" not found in "okc-juju-dev" controller

How i can change the rate limit ?
