[rancid] Cisco Nexus crashing due bug triggered by rancid
2012-06-02 17:02:36 GMT
Cisco Nexus 5.0.3 or later has a bug where if you run 'show version' 10,240 times, the Nexus will crash. Rancid includes 'show version' as part of its info gathering; today one of my production 5596UPs crashed due to this bug (CSCts72635).
"If callhome is configured and sending alerts (like temperature alarms), the bios_daemon can be triggered in this process. The problem is that bios_daemon opens a file descriptor and it does not close.
"show version" is another way to trigger this.
The problem will occur after 10240 callhome alerts or instances of running "show version"
5.0(2) does not have this problem. "
