Narrative:
Clearance delivery gave us a 6000' altitude restriction which we read back to cvg. First officer copied and I confirmed the 6000' restriction. After takeoff we checked in with departure with our passing altitude and 'climbing to 6'. We got some vectors. During climb, I called 'out of 5 for 6' and we got not much acknowledgement. There was lots of chatter between departure control and 3-4 other aircraft, all level at 5, 6, and 7 thousand. Both the first officer and I watched traffic off our left wing slowly converging. The traffic called us out to departure at about 1 mi range. At this time, the departure controller told me I 'busted' my altitude and gave us a turn to the right 090 degree away and a climb to 12000. 1) I don't know what caused the problem except for a lot of traffic, a lot of radio calls, and maybe some confusion on the part of the cvg controller and myself. 2) to correct this problem, I believe cvg needs some more controllers with each controller getting less of a workload. This guy was almost talking nonstop. Supplemental information from acn 138634: passing 5000' the captain called departure advising them we were passing 5000' for 6000' looking for higher. We were given a turn to 360 degree. After rolling out heading 360 degree the captain noticed the air carrier medium large transport which had taken off before us flying about 3 mi at our 9-10 O'clock position, same direction. There was an obvious mixup in communications, but I don't know where it occurred. The controller was very busy and there were several aircraft in the vicinity. Perhaps the workload was too much and a change in our altitude clearance was never passed on.

Title: AFTER DEP ACR CLIMBED TO AN OCCUPIED ALT RESULTING IN LESS THAN STANDARD SEPARATION.
Narrative: CLRNC DELIVERY GAVE US A 6000' ALT RESTRICTION WHICH WE READ BACK TO CVG. F/O COPIED AND I CONFIRMED THE 6000' RESTRICTION. AFTER TKOF WE CHECKED IN WITH DEP WITH OUR PASSING ALT AND 'CLIMBING TO 6'. WE GOT SOME VECTORS. DURING CLIMB, I CALLED 'OUT OF 5 FOR 6' AND WE GOT NOT MUCH ACKNOWLEDGEMENT. THERE WAS LOTS OF CHATTER BETWEEN DEP CTL AND 3-4 OTHER ACFT, ALL LEVEL AT 5, 6, AND 7 THOUSAND. BOTH THE F/O AND I WATCHED TFC OFF OUR LEFT WING SLOWLY CONVERGING. THE TFC CALLED US OUT TO DEP AT ABOUT 1 MI RANGE. AT THIS TIME, THE DEP CTLR TOLD ME I 'BUSTED' MY ALT AND GAVE US A TURN TO THE RIGHT 090 DEG AWAY AND A CLIMB TO 12000. 1) I DON'T KNOW WHAT CAUSED THE PROBLEM EXCEPT FOR A LOT OF TFC, A LOT OF RADIO CALLS, AND MAYBE SOME CONFUSION ON THE PART OF THE CVG CTLR AND MYSELF. 2) TO CORRECT THIS PROBLEM, I BELIEVE CVG NEEDS SOME MORE CTLRS WITH EACH CTLR GETTING LESS OF A WORKLOAD. THIS GUY WAS ALMOST TALKING NONSTOP. SUPPLEMENTAL INFORMATION FROM ACN 138634: PASSING 5000' THE CAPT CALLED DEP ADVISING THEM WE WERE PASSING 5000' FOR 6000' LOOKING FOR HIGHER. WE WERE GIVEN A TURN TO 360 DEG. AFTER ROLLING OUT HDG 360 DEG THE CAPT NOTICED THE ACR MLG WHICH HAD TAKEN OFF BEFORE US FLYING ABOUT 3 MI AT OUR 9-10 O'CLOCK POSITION, SAME DIRECTION. THERE WAS AN OBVIOUS MIXUP IN COMS, BUT I DON'T KNOW WHERE IT OCCURRED. THE CTLR WAS VERY BUSY AND THERE WERE SEVERAL ACFT IN THE VICINITY. PERHAPS THE WORKLOAD WAS TOO MUCH AND A CHANGE IN OUR ALT CLRNC WAS NEVER PASSED ON.
