Jenkins seems to hang

[GerdP]

I see no progress for some hours, JOSM r19001 is in the queue since 9 a.m.

I killed the integration job that seemed to be stuck (~2 days).

For the record, it was stuck in check-plugins:

Is it possible that there are too few free executors? I think the job is still waiting for a free one.

[taylor.smock]

I didn't kill the rest of the queue. We have a single executor, so we go through the queue serially.

I could look into adding my home server as an executor, but I'd want to go through the current jobs to make certain they can be run on a separate machine.

OK, that explains it. I'll just wait ;)

Not necessary. The server could also do more than one queue, but why? ;-)

I was just confused because Jenkins showed 4 different task which are "executed" but only one was really making progress.

I think being confused by Jenkins is totally normal. It's rather an exception if one understands what's going on. ;-)

[taylor.smock]

IIRC, most of the jobs that were "executing" were parent jobs that were waiting on their children to execute. There was only one that was actually doing anything.
