Summary

When an SVN repository's branch URL is not the default, or no branches are being used, Bamboo continuously tries to perform its first-time branch detection procedure (to determine what repository branches pre-exist the build plan) and never ceases this check.

Workaround

Special marker records exist in the database and these need to be removed to stop Bamboo from continuing to poll the repository.

DELETE FROM VCS_BRANCH WHERE NAME='initialize.chain.branches@@!3.141519' AND CHAIN_ID=<id of BUILD plan record>;
