I had an alarm on an ASR1002 in one of our sites in Australia can't recall but it was a known bug, something like punt_linux on the NMS screen when I contacted TAC just acknowledged it, free memory was sufficient enough though
The memory architecture on these beasts is complex and depends on models and the line cards installed as you have RP's per line card then the memory is shared and protected in case one process fails which means the whole router does not die as what were used to in regular routers.. -- BR Tony Sent from my iPad > On 2 Jan 2014, at 18:03, marc abel <[email protected]> wrote: > > Slightly OT, but has anyone had any memory issues with ASR 1K's?
