I have a router 2800, The problem is high CPU utilization especially for "check heap" My question is, hardware failure? Like the memory... or need change the router
Find information about the topic but I do not understand ...
Check heaps: Checks the memory every minute. It forces a reload if it finds processor corruption.
Most of the CPU is being used by interrupts.
CPU utilization for five seconds: 70%/68%; one minute: 70%; five minutes: 70%
From this, 68% is being used by interrupts.
Take a look at the link below and check the steps mentioned.
