Issue Summary

When starting a fresh install of Bitbucket DC up for the first time, the search StartupChecksJob may fail to create indexes due to a rare race condition caused by asynchronous search indexing queue events attempting to index documents prior to the job being ready.

Steps to Reproduce

Start up a fresh installation of Bitbucket DC that's been configured to point to an external OpenSearch server.

Expected Results

Bitbucket should start up with all the expected indexes created succcessfully.

Actual Results

Some indexes may fail to be created with the following error.

2025-10-22 08:03:49,226 ERROR [Caesium-1-2]  c.a.b.i.s.i.IndexingSynchronizationService Failed to create indexes: ''[resource_already_exists_exception]''

The failure causes the job to exit early and fail to write create remaining indexes causing other search features to not function properly

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
