When I try to execute Facebook HHVM hackficator from PHP I get this error
Fatal error: exception Failure("unstable www state before modification")
I googled error and found reference inside the code written in OCaml
https://github.com/facebook/hhvm/blob/master/hphp/hack/tools/hackificator/hackificator.ml
but I have no idea does that mean?, but I do see a reference to www
This means that hh_client
executable was called and returned something other than "No errors!"
