Frequency 133.52 of den ARTCC was literal chaos. It appeared that the center controller was on 2 frequencys, overwhelmed. Due to many overlapping conversations, relayed messages were necessary, some changeovers were missed and we could not acknowledge an ATC request, none of this created a major problem, however this communication chaos should not be permitted to occur. Clearly this poor controller was overloaded to a dangerous degree that degraded safety, could have created a serious mistake. It would only be our guess that center staffing around xaooz in den ARTCC was inadequate.

Title: ACR WDB COMPLAINS ABOUT WORKLOAD AND RESULTING COM PROBLEMS WITH ZDV.
Narrative: FREQ 133.52 OF DEN ARTCC WAS LITERAL CHAOS. IT APPEARED THAT THE CTR CTLR WAS ON 2 FREQS, OVERWHELMED. DUE TO MANY OVERLAPPING CONVERSATIONS, RELAYED MESSAGES WERE NECESSARY, SOME CHANGEOVERS WERE MISSED AND WE COULD NOT ACKNOWLEDGE AN ATC REQUEST, NONE OF THIS CREATED A MAJOR PROB, HOWEVER THIS COM CHAOS SHOULD NOT BE PERMITTED TO OCCUR. CLRLY THIS POOR CTLR WAS OVERLOADED TO A DANGEROUS DEGREE THAT DEGRADED SAFETY, COULD HAVE CREATED A SERIOUS MISTAKE. IT WOULD ONLY BE OUR GUESS THAT CTR STAFFING AROUND XAOOZ IN DEN ARTCC WAS INADEQUATE.
