Hi Denis, Winston, all,
Right. So I propose that the tycho-gmp.gmf.tooling
<https://hudson.eclipse.org/hudson/view/Tycho%20+%20Maven/job/tycho-gmp.gmf.tooling>
job be moved over to our Sandbox so that its memory consumption does
not impact our Hudson instance. Any objections?
How much trouble does this cause to other jobs? Is this job the only
responsible for Hudson being slow? Would removing from Hudson save the
world?
If yes, then I think it is fair to move it TEMPORARLY to the sandbox
while the issue is not fixed. But I'd be OK with that just if someone
can promise to the GMF Tooling team that the issue (which is in GMF
build? in GMF job? in Maven? in Hudson?) will be fixed in a short delay,
otherwise the CI job for GMF Tooling will be forever in a sandbox, it'd
have a bad effect on the project. Also, be sure that if GMF Tooling job
is moved to sandbox, the same problem will happen on sandbox...
If no, then it seems that the job does not cause real trouble, then
let's keep it as it and keep on enjoying life while Hudson folks improve
the memory consumption.
Is there any benefit in blaming this job and moving it to sandbox?
Winston,
Correct me if I'm wrong, but since the build happens in a forked process
in Hudson, it does not consume memory by itself. Then the problem is
clearly in Hudson or one of its plugins, isn't it? So the Maven/Tycho
build by itself is not the culprit. If the memory is consumed by Hudson
JVM, then the issue in is Hudson.
Is there something we could change in configuration of the job to make
it consume less memory?
About the tests, GMF-Tooling has 431 tests, I am not really sure. Some
other projects probably have more tests on this Hudson instance and
don't have the same problem. But maybe the content of test reports is
bigger in GMF Tooling (more execution traces maybe?) causing this huge
memory consumption.
Any help is appreciated. You can get me on Skype: mickael.istria
