Symptom: A single-bit ECC error in NP instruction memory was not repaired properly and thus continues to be detected and reported repeatedly. Here is an example: prm_server_ty: %PLATFORM-NP-3-ECC : prm_ser_check: Single-bit ECC error detected: NP 7, block 0x18 (MDF), offset 1, memid 51, name INSTRUCTION_MEM1, addr 0x0000004d, bit 35, ext info 0x00000001 0xffffffff 0xffffffff 0xffffffff, action 0 (Fix) There are no functional side effects, but the error will continue to be detected and reported over and over. Conditions: This problem is specific to Typhoon linecards. There is no specific trigger for the underlying error as it is a rare and random hardware occurrence.
