Subject: nsNotifyRestart traps generated in place of link up/down.

Hi Experts,

In our product we are using Net-snmp 5.7.3 and today a customer is hitting a strange issue with
some undesired nsNotifyRestart traps being generated, in place of link up/down traps,
when performed shut/noshut operations on selected intetrface.

Here is the SNMP v1 config Used by Customer:

snmp-server host x.y.z.w snmpComm1ab
snmp-server enable traps snmp linkup
snmp-server enable traps snmp linkdown

Here is the Unwanted nsNotifyRestart trap getting generated when performed interface shut/noshut operations

2019-02-08 17:07:19 x.x.x.x(via UDP: [x.x.x.x]:x->[x.x.x.x]:x) TRAP, SNMP v1, community snmpComm1ab
        NET-SNMP-MIB::netSnmpNotificationPrefix Enterprise Specific Trap (NET-SNMP-AGENT-MIB::nsNotifyRestart) Uptime: 0:00:05.44

Any thoughts when "nsNotifyRestart" traps are generated and why they are blocking the expected link up/down traps here ?
And how to proceed forward on this case with customer ?

Could you please advise.

Thanks,
Kiran
