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).<br>
<br><span>"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.<br><br>"show version" is another way to trigger this.<br><br>The problem will occur after 10240 callhome alerts or instances of running "show version"<br>
<br>5.0(2) does not have this problem.
