Hi Wes I have performed snmpwalk on 2 different hosts . snmpd was started with -DALL option. Please find the logs. Can you let me know if there are obvious difference between two set of logs. Can upgrade to net-snmp 5.9 resolve the issue ?

The behavior is same Make sure the engineid being reported is actually what you expect (don't know why it would be different, but...) Can you also see if the engineid boots and time values look good both incoming and outgoing? IE, are they syncing ok like they should? > * Deleted the user and re-added with MD5/DES.
