Post #1 of 2 (1366 views) Permalink Continued SegV exception On 7206 LNS My Cisco 7206VXR with NPE-G2 runs as an LNS terminating PPPOE sessions. It also terminates a DS3 used for data T1s. About once a week or so, a SegV exception happens, and the router resets itself. I have no idear why. The documentation says this is invariably a software error, and we have upgraded from c7200p-spservicesk9-mz.150-1.M.bin to c7200p-spservicesk9-mz.150-1.M3.bin, but he problem continues. There seems to be no pattern to it. Sometimes, it happens under heavy load. Sometimes, it happens under very little load in the middle of the night. Sometimes, it happens once in two weeks. Sometimes, it happens thrice a day. Usage is still pretty decent, averaging at abotu 30%. Does anyone have an idea about what we should be looking at? Should we be using a different firmware altogether?
