Narrative:

My sector was very busy and I gave aircraft #1 a descent from 15000 ft to 12000 ft (it was actually a crossing restr). I noticed a VFR at 12500 ft squawking XXXX east of hto heading west. At the time I felt that aircraft #1 would be out in front of aircraft #2 (aircraft #1 was heading northwest). My sector became even more saturated with traffic and I got busy dealing with another aircraft (C160) 40 mi southwest hto heading north. Aircraft #3 was asking for a descent. I cleared aircraft #3 to descend from 110OO ft to 9000 ft (expediting) because of head on traffic at 10000 ft. Aircraft #3 did not hand off to nyc approach so I had to make a manual handoff to nyc approach. When I was busy with aircraft #3, aircraft #1 had an RA with aircraft #2. I feel my sector's complexity was high and I was distraction with aircraft #3 automation problems and this led to my misjudgement with aircraft #1.

Title: ZNY ARTCC RADAR CTLR WORKING A BUSY SECTOR HAS A TCASII RA EVENT OCCUR WHILE ON THE LANDLINE COORD A HDOF.

Narrative: MY SECTOR WAS VERY BUSY AND I GAVE ACFT #1 A DSCNT FROM 15000 FT TO 12000 FT (IT WAS ACTUALLY A XING RESTR). I NOTICED A VFR AT 12500 FT SQUAWKING XXXX E OF HTO HDG W. AT THE TIME I FELT THAT ACFT #1 WOULD BE OUT IN FRONT OF ACFT #2 (ACFT #1 WAS HDG NW). MY SECTOR BECAME EVEN MORE SATURATED WITH TFC AND I GOT BUSY DEALING WITH ANOTHER ACFT (C160) 40 MI SW HTO HDG N. ACFT #3 WAS ASKING FOR A DSCNT. I CLRED ACFT #3 TO DESCEND FROM 110OO FT TO 9000 FT (EXPEDITING) BECAUSE OF HEAD ON TFC AT 10000 FT. ACFT #3 DID NOT HAND OFF TO NYC APCH SO I HAD TO MAKE A MANUAL HDOF TO NYC APCH. WHEN I WAS BUSY WITH ACFT #3, ACFT #1 HAD AN RA WITH ACFT #2. I FEEL MY SECTOR'S COMPLEXITY WAS HIGH AND I WAS DISTR WITH ACFT #3 AUTOMATION PROBS AND THIS LED TO MY MISJUDGEMENT WITH ACFT #1.
