Hi Harry, Unfortunately, I probably cannot provide any further insight here. I just saw what looked to be a raw system level error. I am too out of date with OAE to know anything about the actual tests.
This looks like it might actually be another system-level problem, though. Multiple processes opening the file descriptors or something: https://github.com/gruntjs/grunt-contrib-watch/issues/75#issuecomment-17826879 Maybe try to kill any previous processes that were running? These kinds of things that spawn lots of processes and/or watch lots of files are usually tricky.
