Hi Shayne, I vaguely VPB having inbuilt support for keeping a lid on the number of open file handles. I don't recall the specifics though, it's a couple of years since I wrote this part of VPB, perhaps we need to update the mechanism to query how many open files are supported and adjust it so it's osgdem task has a portion of this total so that when multiple osgdem's run they don't end up eating up all the file handles between them.
