Current Behavior

Using Fleet v0.12.11 in Rancher 2.11.5, we observe the fleet-controller emitting an endless stream of "Unchanged bundledeployment" logs:

The message rate is on the order of about 3.5 million messages per hour.

I can imagine there are three possible explanations, but I'm open to others:

• This is a new (or newly verbose) info-level message (maybe it was at "debug" earlier?) and it's working as expected, in which case the resolution is to bump the log level to 'warn' to suppress these.
• There is some weird code path where maybe a misconfiguration in a GitRepo or Bundle is causing the fleet-controller to loop endlessly
• There is a bug in fleet-controller causing the endless loop

Expected Behavior

"Unchanged bundledeployment" log messages should only be emitted, at most, once per GitRepo's pollingInterval

Steps To Reproduce

1. Install Fleet v0.12.11 in Rancher 2.11.5
2. Add a few GitRepos (most of our have pollingInterval=30m)
3. Watch fleet-controller logs

Environment

- Architecture: x86_64
- Fleet Version: v0.12.11
- Cluster:
  - Provider: RKE

Observe the message rates across multiple Rancher masters:

The stepped increases correspond to Fleet v0.12.11 being introduced via Rancher 2.11.5 as we rolled it out

This is a known issue that was fixed in #3796
That was released in Fleet 0.13.0 onwards.

I would suggest to upgrade to Rancher 2.12 and retest.
