recently, I found lots error info frequently appears in "sh log" result.

It appears like this :

interrupt Packet Parser block interrupt

Dec 28 14:44:19.735: %EARL_L3_ASIC-SP-3-INTR_WARN: EARL L3 ASIC: Non-fatal inter

rupt Packet Parser block interrupt

Dec 28 14:44:47.074: %MLS_STAT-SP-STDBY-4-IP_CSUM_ERR: IP checksum errors
