While processing a query to the IF-MIB's ifXTable, an snmpd core dump and restart occurred.
Minimal impact to SNMP queries. snmpd is automatically restarted.
Occurs if the ifTable's ifAlias attribute is set to a NULL value.
If the ifAlias for a given interface ifIndex has a NULL value, it can be changed to an empty string, or any string, using the snmpset command: snmpset -t30 -v2c -c public localhost IF-MIB::ifAlias.<ifIndex> s ""
snmpd has been modified to check for NULL ifAlias values before attempting to process a set/get SNMP query.
