Hi Stephan,

I did see those time out messages, but not much explanation in the console though. I was wondering why it was taking 160+ minutes in
the first place, but I can't figure out.


Good question.

One more detail from #2699:
13:08:55  Running org.eclipse.jdt.core.tests.dom.RunAllTests
14:38:18  Build timed out (after 169 minutes). Marking the build as aborted.

=> dom tests had been running for 90 minutes without completion and no intermediate sign of life.

For #2687 it "froze" in the middle of model tests (80 min. of quiescence):

06:30:48  Running org.eclipse.jdt.core.tests.model.AllJavaModelTests

08:00:32  Build timed out (after 156 minutes). Marking the build as aborted.

So, we are not looking for general slowness, but more like a bad freeze / deadlockish kind of thing.

Not good.

Looking at the hudson config:

timeout is "elastic": 200% of last non-failing job or 180 min total. Looks good.

I was looking for more options on dumping diagnostics when stuck, but found nothing.
Was it an old PDE/Build option that allowed to do things like take a screenshot when it timeouts?
Thread dumps would be perfect, right? I just filed https://bugs.eclipse.org/515272

Next time it happens, I suggest to search the hudson workspaces in locations like
target/surefire-reports for any traces/dumps/logs. Unfortunately, that information
is lost as soon as the next job starts, so you have to be quick :)

    #2699 has this:

    14:38:18  Build timed out (after 169 minutes). Marking the build as aborted.

    this is from #2687:

    08:00:32  Build timed out (after 156 minutes). Marking the build as aborted.

    I don't see a reason in #2697, though.

    best,
    Stephan
