Description (partial)


I have a back to back connected 1xCHSTM1/OC3 spa in SIP 400. I configured 4 T1 serial links and added them to two diffierent multilink bundles ( 2 links per bundle ). While moving the links across the bundles, I was seeing following error messages sometimes.
SLOT 3: 14:58:39: %SPA_CHOC_DSX-3-HDLC_CTRL_ERR: SPA 3/1: 6 TX Chnl Queue Overflow events on HDLC Controller were encountered.


The messages were seen only when we try to move the member links in the presence of traffic
