Narrative:

Aircraft #1 and #2 were previously separated and aircraft #2 given climb to FL410. However, both #1 and #2 reconverged at or near the gup VORTAC. I was unaware and allowed myself to be distracted by other duties. Conflict alert was activated almost upon loss of separation. Immediate vectors and climb for #1 were issued to separate the aircraft. Aircraft were then cleared on course.

Original NASA ASRS Text

Title: CTLR ISSUED A CLB TO A CGA JET THROUGH AN OCCUPIED ALT RESULTING IN LTSS. THE CTLR BECAME BUSY WITH OTHER ACFT AND FAILED TO SEE THE 2 ACFT CONVERGING.

Narrative: ACFT #1 AND #2 WERE PREVIOUSLY SEPARATED AND ACFT #2 GIVEN CLB TO FL410. HOWEVER, BOTH #1 AND #2 RECONVERGED AT OR NEAR THE GUP VORTAC. I WAS UNAWARE AND ALLOWED MYSELF TO BE DISTRACTED BY OTHER DUTIES. CONFLICT ALERT WAS ACTIVATED ALMOST UPON LOSS OF SEPARATION. IMMEDIATE VECTORS AND CLB FOR #1 WERE ISSUED TO SEPARATE THE ACFT. ACFT WERE THEN CLRED ON COURSE.
