When git-plugin is configured to use the integration branch feature and the there are multiple candidate revisions and the merge fails an endless number of builds are scheduled. As you can see from the log below and new build is scheduled before the merge fails. And the new scheduled build will schedule a new build and fail for the exact same reason.... Endless loop....

The build is configured to merge all branches matching /order/* and /bug/* into project/man/integration464 branch

Here's the log from jenkins build:
