Re: [cross-project-issues-dev] tycho-gmp.gmf.tooling builds consumes enormous amount of memory

Hi Denis, Winston, all,

Right.  So I propose that the 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?

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
