The PR title correct logic introduced with SKARA-572 can end up trying to correct the title forever. An observed case is where the JBS title ends with a trailing space. When trying to update the PR title to include this trailing space, it will be stripped by GitLab and no update will actually be done. This will then get retried again and again.

It may be a good idea to check if the title actually changed as intended, and if not, stop trying to fix it.
