Narrative:

Aircraft Y was a parachute aircraft that was shipped to us out of 10;000 feet. The aircraft climbed to 14;500 feet. Aircraft X was climbing southbound in close proximity to the jump aircraft. The controller advised aircraft Y of aircraft X; and the pilot responded they had just released the jumpers. Aircraft X checked on climbing to 12;000 feet. The controller advised aircraft X of the parachute aircraft. Aircraft X advised the controller they were responding to a TCAS resolution and descending. Aircraft X descended to 10;500 feet. Aircraft Y was at 11;500 feet and descending.this is not the first instance of [the approach facility] running aircraft in close proximity to parachute aircraft that they have shipped to us.

Title: Aircraft Y; a VFR parachute aircraft; was descending out of 11;500 feet. Aircraft X; an air carrier; was below Aircraft Y while climbing on a converging heading. Aircraft X received a TCAS/RA on Aircraft Y and responded accordingly. Aircraft Y released parachutists in the immediate vicinity of the Aircraft X's departure route.
