Nexus 5548 Restart Itself

[tgut]

Hello Everybody,

I have a Nexus 5548

Recently restart itself for no reason

I ran the command:

sh system reset-reason

----- reset reason for Supervisor-module 1 (from Supervisor in slot 1) ---

1) At 469203 usecs after Sat May 11 14:02:07 2013

    Reason: Reset triggered due to HA policy of Reset

    Service: eth_port_sec hap reset

    Version: 5.1(3)N1(1a)

sh processes log details

Start type: SRV_OPTION_RESTART_STATELESS (23)

Death reason: SYSMGR_DEATH_REASON_FAILURE_SIGNAL (2)

Last heartbeat 6.09 secs ago

RLIMIT_AS: 189894144

System image name: n5000-uk9.5.1.3.N1.1a.bin

I've been searching in Google/Cisco about the eth_port_sec hap reset and cannot find any reason, just something about the same error but in different technology:

http://www.cisco.com/en/US/docs/unified_computing/ucs/release/notes/OL_25363.html

CSCub36000

SNMP polling on eth_port_security objects no longer causes an eth_port_sec hap reset.

I just to want to be sure, is the same reason...

Or do you know something than can cause it on a Nexus Switch???

I Appreciate you help!

Hello Tonoguate,

I think what you experienced was bug: CSCua70120

symptom:

Unexpected reset with error message

%SYSMGR-2-SERVICE_CRASHED: Service "eth_port_sec" (PID 3258) hasn't caught signal 6 (core will be saved).

Conditions:

Port-security feature being configured

Workaround:

Unknown

This was found in 5.1(3)N1(1). Almost identical to your version.

Sadly that is about all the information provided. Under that bug, this information is given: Duplicate bug CSCua70120 is superceded by CSCty83755 At present, CSCty83755 is under review, hence the details are not shown.

CSCty83755 is not viewable. So though this answers no questions for you, but I would bet my money this is the bug you hit.
