Subject Re: volunteering for ASF Jenkins farm service maintenance
Date Sun, 13 Apr 2014 19:49:49 GMT
Hi all,

Like Hervé I feel that the current state of Jenkins at the ASF is not
good enough. The main problem, judging by the threads on builds@, are
the Windows slaves. I see two major problems here:

1. The stability of the servers - they seem to go offline quite often,
requiring manual restarts. Not sure where this problem lies though.

2. Misuse of the available resources. Just have a look at the load
statistics for windows1:
It currently has an avarage queue length of 12! With only 2 machines
available (currently only 1) we need to limit the amount of work the
can be put on them. Again I see two parts of the problem:

2.a Extremely long running builds, i.e. builds that take 10+ hours to complete.

2.b Timer started jobs. If these slaves are to be used as *build*
servers we cannot afford to allow builds to run when there have been
no change in version control and no changes in upstream jobs.

Note: the examples above were selected randomly from the currently
running jobs. I'm sure there are lots of other projects doing similar
things. It is not my intention to single out these projects, but to
provide examples to back up the points I'm trying to make.
