Chris Cornell's stalker is on the loose and could show up at his doorstep at any minute ... this according to the FBI.
The feds contacted Cornell Wednesday to let him know Jessica Robbins -- who was charged with stalking Cornell in 2014 -- is on the loose again. Robbins allegedly sent hundreds of online threats to Cornell and his family, and drove 7 hours in a failed attempt to get inside his home.
We're told Robbins removed her court-ordered GPS ankle monitor and bailed on a Tuesday appearance in NYC federal court.
The FBI obtained a bench warrant for her arrest the next day, and we're told U.S. Marshals and Florida authorities are working together to track her down.
The timing is problematic ... Cornell has 2 shows in Florida soon -- both within driving distance from Tampa, Robbins' last known location.
