Yes, I was thinking of the kill kommand. The OP stated that the jobs are "triggered successfully one after another", which led me to the assumption that they are somehow put into a queue, and Tk::ExecuteCommand of the second job is done only after the first has completed. At least this would be an explanation for the reported behaviour.

I think we need more info (source) from Janish to be able to help.
