CP continuous messages "Last device changed"

Hi Folks

 

Good Day!!!!!!!!!!

 

Recently my SilkWorm 48K started flodding messages "SLOT 5 | FID 128, INFO, HDFC_BLR03,  The last device change happened at :" (atleast 1000 messages per day)

 

Because of that flow of messages i observe "SCN queue overflow for process snmpd" message even

I dont see any changes happening on the switch.

I am not able to correlate as the messages are related CP blade

There are no errors found on switch ports even.

 

 

 

Can some one help me T-shoot the problem; Any advices on it are most welcom.

SNMP-1008 error message, as per my experience is related to member hang in the config.

 

"nshow" command give the output if all member Alias/Zone are audited in the Name Server.

 

I would suggest to run SAN-Health, to identify such problem.

Hi,

Did you located the source of the issue?

What did the fabriclog --show report?

I have this same thing, and it makes the logs very hard to parse.
