I am seeing a new problem I have never encountered befoer I loaded the latest code on our systems. For the last 36 hours we have been seeing each chassis drop 48 channels at semi-regular frequencies. Two chassis's are doing this after about 12 hours, the otehr two after about 24. The similarity between all the chassis's are 48 channels on dsp's served by channelized T1, but I don't know what any of that has to do with the problem. I have looked at the performance counters and none of the T1 stats show any errors for the last 24 hours. I can't find any reason for the problem other than the evidence of a few folks complaining about disconnects again and the mrtg indications of the problem. Any ideas as to where I can look to diagnose this problem? I really appreciate any and all responses.
