[rancid] Cisco CPU goes crazy

Fri May 4 21:00:42 UTC 2018

If you have AAA accounting configured, you can see the commands in the accounting logs.

See also the command “show history all | begin rancid” (my rancid username in AAA is “rancid” and my rancid version is 3.4, so you might see different output).

Cisco can help you with this. You'd have another window open looking at the process table information at the time that rancid is running. They have a continuous mode.

Hello,

Rancid version is 3.7 on Linux.

When Rancid logs on to the Cisco switches listed bellow, the CPU goes crazy for a few seconds which causes some processes like OSPF to converge.

suppose you're hitting a IOS bug.  figure-out which command causes the

high cpu usage and open a ticket with cisco.
