Hi all,

We recently upgraded our Jenkins to 2.7.4 and Job DSL 1.51 and Jenkins now has a non heap leak coming from loaded classes.


Using VisualVM with a heap dump from Jenkins shows all of the classes and closures used in our seed jobs to be each loaded many times over, with instance counts of 0. We are not using any meta programming/monkey patching (but I am double checking this), so I am unsure if this is the same issue as https://issues.jenkins-ci.org/browse/JENKINS-23762.

Any thoughts or advice?


Thanks,
Chris

I've been having the same issue since upgrading. No meta programming here either. I'm having Jenkins restart itself every couple days as a workaround.

What version ranges are involved in your upgrade case? Perhaps we can help narrow this down to a changeset.
My upgrade range was massive and not terribly helpful (Jenkins 1.570 to 2.7.4 and Job DSL 1.25 to 1.51).

I'm not sure. I usually upgrade to the latest every month or two, and I can't remember exactly when this issue started happening. I feel like it was probably around the time we switched from Jenkins 1.x to 2.x. Right now we're on Jenkins 2.16, DSL 1.51.

I think this is going to be fixed in Groovy 2.4.8, but has not been releaes yet.

Can you test the workaround and report the results?

Daniel

Adding -Dgroovy.use.classvalue=true seems to fix it for me. Thanks!
