| This is probably best answered through the Jenkins user mailing list or the Jenkins chat channels. Alternately, if you're running a CloudBees product, you could open a CloudBees support ticket. Intermittent failures typically involve investigations of several possible causes, looking for hints in log files and elsewhere which will explain the intermittent failure:
- Are there log entries on the git server at about the same time which hint at an overload condition?
- Are there authentication log entries on an LDAP or active directory or other server which might get more details on why the credentials were rejected?
- Are there more details logs on the Jenkins server which might hint at global issues (low memory, etc.) which might cause the problem?
- Are the authentication failures specific to a single agent or a subset of agents?
All those topics are best addressed in the mailing list or the chat channels. |
