How exactly are you managing to produce this? It works perfectly fine on lxplus and the Imperial group machines. With no extra information there is nothing we can do. There must be something in your local environment. Are you starting Ganga in a totally clean shell?

[heistera]

I've just started ganga. Ganga then processed 11 jobs with > 1000 sub jobs before starting ... nothing else ...

It is a bit odd to start ganga from within the gangadir, but I do not think it should matter.

Otherwise, my suspicion is also that you have something in the environment that upsets ganga.

[heistera]

I did not change anything in my environment for some time. I am controlling all relevant scripts with git. Since my report it never happened again.
