Description:	Repeatedly doing a local channel chain of 300 eventually causes the system to be bogged down doing CDR processing. It would appear that create_candidates_for_bridge() needs to be improved since the number of buckets in the the active_cdrs_by_channel container was increased.
Comments:	By: Richard Mudgett (rmudgett) 2013-09-09 14:35:29.037-0500 See ASTERISK-22482 for local channel chain creation. By: Matt Jordan (mjordan) 2013-09-12 18:58:12.296-0500 Creating the candidates from the channels in the bridge could certainly be done more efficiently. This really needs a two pass look-up: One to get the channels that are in the bridge, the next to get their CDRs from the existing container. That really should prevent the O(n) iteration that occurs currently.
