net-snmp-5.8: broken ErrorMsg at ucd-snmp
No error messages at UCD-SNMP-MIB::prErrMessage in net-snmp 5.8 (Alpine 3.9, 3.10 and edge).
It works fine in nt-snmp 5.7.3 (Alpine 3.8, 3.7)
Steps to reproduce with a configuration to monitor a process:
rocommunity public
proc snmpd
Query proc error messages in Alpine <= 3.8:
snmpwalk -v 2c -c public localhost UCD-SNMP-MIB::prErrMessage
UCD-SNMP-MIB::prErrMessage.1 = STRING:
Query proc error messages in Alpine >= 3.9:
snmpwalk -v 2c -c public localhost UCD-SNMP-MIB::prErrMessage
UCD-SNMP-MIB::prErrMessage = No Such Instance currently exists at this OID
It seems to be related with this upstream bug: https://github.com/net-snmp/net-snmp/issues/26
