I suspect the problem may be race conditions being set up between https://github.com/qgis/QGIS/blob/master/python/plugins/processing/algs/grass7/Grass7Utils.py and https://github.com/qgis/QGIS/blob/master/python/plugins/processing/algs/grass7/Grass7Algorithm.py. It attempts to use an existing session and shared mapset which could be problematic from the sounds of things. It might be an idea to add an optional parameter to grass algorithms to not use shared mapsets and create a new mapset for each process?
It just came in yesterday :)
[GRASS-user] New CLI option --tmp-location in 7.5 to enhance --exec
Perhaps this approach will solve the issues?
