The VM processes are apt to leak for reasons unknown: Maybe Jenkins can't track the shell games I have to try play with Squeak. Suggestions for improvement actively sought.
I think it would be worth restarting jenkins, but disabling all but one of these VM-related processes until this is fixed. It would help if you could give us some pointers about what is wrong, and where to start looking around.

I restarted Jenkins so the build.squeak.org site will be active, but we really need to clean this up.
Frank, do you agree with Levente's suggestion to disable projects until the issue is resolved?
I'm not in a position to do much about things until week after next: personal emergency. Do whatever you think is appropriate to mitigate the problem.
It will probably boil down to an exception causing a debugger, and since Squeak's command line support is... not adequate, it's impossible to debug without someone manually running the same process on a local machine, hacking the build scripts to run headfully. This has been my experience, at least, whenever we have had this problem.
If someone's sufficiently motivated, they should be able to follow the instructions at https://github.com/squeak-smalltalk/squeak-ci/ (and hit me if they're not) and run something like "rake clean build test_package[Control]" to reproduce the issue. You'll need to edit lib/squeak-ci/build.rb replacing the vm_args method with this:
def vm_args(os_name) [] # Force headful end
Only bother if you're comfortable with installing a Ruby. Diagnosing and solving the problem will require more knowledge about process spawning and subshells than I possess. run_image_with_cmd is almost certainly the source of the problem: https://github.com/squeak-smalltalk/squeak-ci/blob/master/lib/squeak-ci/buil...
