Symptom
A Cisco Nexus 5000 switch might unexpectedly fail with kernel panic. This has been known to be seen when a device polls the nexus switch every few minutes. In addition polling the switch frequently could trigger the issue as well.
The root cause is a timing issue internally to the switch.
Conditions
Nexus 5000 switch being polled from the CLI or via SNMP. The following commands could potentially trigger the kernel panic:
show int trans detail | no-more
show interface | include "interface reset"
show interface snmp-ifindex
Workaround
Reducing the polling frequency would reduce the chances of running into this timing issue.
