Matrix parent takes executor slot and blocks children

    XMLWordPrintable

Details

    Description

      Not sure when the behaviour changed, but the parent job used to take an extra "free" slot. Now it's taking an actual slot, which can end up being the only slot that one of its children can use, leading to an effective deadlock.
