Narrative:

At the time of the incident, I was conducting OJT on radar east. Small transport X (BE20) was turned to a heading of 070 degrees. Air carrier Y (MD88) was handed off to the east side and subsequently handed off to ZFW utilizing automated information transfer procedures. Authority/authorized a higher altitude for X reference aircraft, en route to mlu climbing to 13000 ft and slower. ZFW authority/authorized X to climb to FL210 reference Y. We informed ZFW that Y would remain north of X. Y was observed climbing out of 12000 ft. X was instructed to maintain 13000 ft to allow Y to out climb him. Y was observed climbing out of 14400 ft and I expected Y to continue climb. X was then instructed to climb to FL210 and switched to ZFW. Y was observed leveling off at 15000 ft and X was climbing out of 13200 ft on a converging course. ZFW was informed that X was climbing to FL210 and questioned if ZFW was going to stop X.

Original NASA ASRS Text

Title: SMT X HAD LTSS FROM ACR Y. SYS ERROR.

Narrative: AT THE TIME OF THE INCIDENT, I WAS CONDUCTING OJT ON RADAR E. SMT X (BE20) WAS TURNED TO A HDG OF 070 DEGS. ACR Y (MD88) WAS HANDED OFF TO THE E SIDE AND SUBSEQUENTLY HANDED OFF TO ZFW UTILIZING AUTOMATED INFO TRANSFER PROCS. AUTH A HIGHER ALT FOR X REF ACFT, ENRTE TO MLU CLBING TO 13000 FT AND SLOWER. ZFW AUTH X TO CLB TO FL210 REF Y. WE INFORMED ZFW THAT Y WOULD REMAIN N OF X. Y WAS OBSERVED CLBING OUT OF 12000 FT. X WAS INSTRUCTED TO MAINTAIN 13000 FT TO ALLOW Y TO OUT CLB HIM. Y WAS OBSERVED CLBING OUT OF 14400 FT AND I EXPECTED Y TO CONTINUE CLB. X WAS THEN INSTRUCTED TO CLB TO FL210 AND SWITCHED TO ZFW. Y WAS OBSERVED LEVELING OFF AT 15000 FT AND X WAS CLBING OUT OF 13200 FT ON A CONVERGING COURSE. ZFW WAS INFORMED THAT X WAS CLBING TO FL210 AND QUESTIONED IF ZFW WAS GOING TO STOP X.
