      Notes

      Workaround

      Option #1. Disable branch detection altogether

      1. Start Bamboo with atlassian.bamboo.branch.detection.disable system property set to true.

      Option #2. This problem can be controlled by changing the branch detection interval:

      1. Overview -> Settings -> General configuration: Field "Branch detection interval".
      2. The default value is 300s. Try increasing it gradually (say 100s) until the problem is controlled.
