In the midst of a chaotic ZFW ATC scene an A321 and an E-135 were both cleared to enter the hold at capti intersection at FL240. Rapidly sequential TA and RA commands to both aircraft prevented a disastrous culmination. Five reports from pilots and controllers involved provided a close up look at both sides of the events. Excerpts from the final ATC report are must reading to obtain the flavor of the event.

Narrative:
We were established in holding pattern over capti intersection at our assigned altitude of FL240. We received TCAS TA which was followed by TCAS RA from traffic descending. We followed TCAS RA commands and descended to 23;500. We notified center; and when clear we climbed back to FL240. The traffic was a crj. Center cleared them to climb and/or maintain FL260. Possible ATC or pilot error; dfw was not taking any aircraft due to weather over the field. It was a very busy time for ATC and air crews. Many aircraft were holding; and making decisions to divert to alternate airports. We ended up diverting to for fuel.
