hi paul,

have had this happen to me. dealing with each error message individually ;

- with regards to the "TM_DATA_PARITY_ERROR" my SE at the time let me know that every other TAC case with this in it they replaced the hardware. TAC did the same for us and it resolved our issue. seems to be the memory was damaged by some external forces.

- with regards to the "excessive reset" and the assertion the controller is "getting reset so frequently" error message which seems to always follow the TM_DATA_PARITY_ERROR Sukumar from cisco was kind enough to respond to my c-nsp post and advise that this is basically straight out misleading and there is a DDTS CSCsg69605 which seems was fixed in 12.2(33.0.4)SRC and above.
