Narrative:
Heavy traffic load. Arrs coming down from 11000' landing bdl, overflts at 5000 and 7000'. Outbnds climbing through arrs. Satellite traffic at barres and westover AFB. Aircraft X jet descending from 11000 to 5000' landed off to arrival controller. Aircraft Y traffic from west to east. Arrival turned jet south crossing the path of en route aircraft. When I noticed the 2, their flight paths had crossed. I don't know if they were in conflict. Problem was I had too much going on for 1 person to handle and arrival wasn't watching my traffic.

Title: ACFT X PROBABLY HAD LESS THAN STANDARD RADAR SEPARATION FROM ACFT Y. ANALYST ESTIMATE 2 MILES HORIZONTAL. PROBABLE SYSTEM ERROR.
Narrative: HEAVY TFC LOAD. ARRS COMING DOWN FROM 11000' LNDG BDL, OVERFLTS AT 5000 AND 7000'. OUTBNDS CLBING THROUGH ARRS. SATELLITE TFC AT BARRES AND WESTOVER AFB. ACFT X JET DSNDING FROM 11000 TO 5000' LANDED OFF TO ARR CTLR. ACFT Y TFC FROM W TO E. ARR TURNED JET S XING THE PATH OF ENRTE ACFT. WHEN I NOTICED THE 2, THEIR FLT PATHS HAD CROSSED. I DON'T KNOW IF THEY WERE IN CONFLICT. PROB WAS I HAD TOO MUCH GOING ON FOR 1 PERSON TO HANDLE AND ARR WASN'T WATCHING MY TFC.
