[JENKINS-36724] Branch indexing hangs

We've been noticing problems with our jenkins branch indexing, which seems to hang from several minutes to hours. We see a lot of Branch indexing jobs on the queue and in the Branch indexing log itself, it shows (what we believe) a complete log with a loading spinner gif at the end.

Not sure what the error is. Would be happy to dig in and provide more info if needed.
