Narrative:
Departed atl en route to aby, climbed to 14000 ft by atl departure and handed off to ZTL at 14000 ft on a heading of 180 degrees. The center controller seemed very busy when I checked on the frequency. We were climbed to 15000 ft, still on heading 180 degrees. The controller made 1 or more xmissions to an itinerant aircraft and was unable to talk to the aircraft. His next hurried transmission was to us, 'turn left heading 0-7-5' was the instruction. It seemed like a large turn but we did not question as we thought it had something to do with the aircraft he was unable to talk to. As we were rolling out on the new heading, the TCASII went off. First a TA and then an RA. Also about this time the controller saw what was happening, questioned our heading and turned us back south. We complied with the RA and also turned south. We saw the aircraft involved but I could not estimate the distance apart. The problem was caused by the controller failing to keep his sector at a level he could handle.

Title: FLC OF A CANADAIR, CL65, WERE TURNED 105 DEGS WHILE LEVEL AT A DEP CLB INTERMEDIATE ALT AND THEN ISSUED A RESOLUTION BY TCASII AT THE SAME TIME ATC CTLR QUESTIONED THE HDG THEY WERE ON AND TURNED THEM BACK TO ORIGINAL.
Narrative: DEPARTED ATL ENRTE TO ABY, CLBED TO 14000 FT BY ATL DEP AND HANDED OFF TO ZTL AT 14000 FT ON A HDG OF 180 DEGS. THE CTR CTLR SEEMED VERY BUSY WHEN I CHKED ON THE FREQ. WE WERE CLBED TO 15000 FT, STILL ON HDG 180 DEGS. THE CTLR MADE 1 OR MORE XMISSIONS TO AN ITINERANT ACFT AND WAS UNABLE TO TALK TO THE ACFT. HIS NEXT HURRIED XMISSION WAS TO US, 'TURN L HDG 0-7-5' WAS THE INSTRUCTION. IT SEEMED LIKE A LARGE TURN BUT WE DID NOT QUESTION AS WE THOUGHT IT HAD SOMETHING TO DO WITH THE ACFT HE WAS UNABLE TO TALK TO. AS WE WERE ROLLING OUT ON THE NEW HDG, THE TCASII WENT OFF. FIRST A TA AND THEN AN RA. ALSO ABOUT THIS TIME THE CTLR SAW WHAT WAS HAPPENING, QUESTIONED OUR HDG AND TURNED US BACK S. WE COMPLIED WITH THE RA AND ALSO TURNED S. WE SAW THE ACFT INVOLVED BUT I COULD NOT ESTIMATE THE DISTANCE APART. THE PROB WAS CAUSED BY THE CTLR FAILING TO KEEP HIS SECTOR AT A LEVEL HE COULD HANDLE.
