My 3700 router keeps getting high CPU utilization (average 50 - 60 %). When it reached 80% or higher, most web sites got time-out and we lost internet connection. Bandwidth monitor from TimeWarner showing usage just about 40% (4 Mbs/10 Mbs):
e0: in from Timewarner telecom 10 Mbs e1: out connnected to 4507 with 21 sub interfaces Config has been changed for years. Few access lists run to prevent sub-int talk together.
If you know any reason may lead to CPU high, please let me know. I want to try all solutions befor it gets worse.
Thank you in advance!
