SNMP Get Response is greater than Get Request + Get Next Request.

Hi Experts,

I am stuck with an issue where SNMP Get Response is greater than the Get Request + Get Next Request. Below is the output (#sh snmp)
Please advise, how is this possible ?
134093437 SNMP packets input
0 Bad SNMP version errors
417218 Unknown community name
254 Illegal operation for community name supplied
0 Encoding errors
774465764 Number of requested variables
0 Number of altered variables
42468880 Get-request PDUs
91148753 Get-next PDUs
0 Set-request PDUs
0 Unknown Security Models
0 Unavailable Contexts
133675965 SNMP packets out
0 Too big errors (Maximum packet size 1500)
975 No such name errors
0 Bad values errors
0 General errors
133675965 Get-response PDUs
1065733 SNMP trap PDUs
0 SNMP trap Proxied
0 Invalid Message Report PDUs
0 Unknown PDU Handler Report PDUs
0 Unknown Context Report PDUs
0 Unsupported Security Level Report PDUs
0 Not In Time Window Report PDUs
0 Unknown Username Report PDUs
0 Unknown Engine ID Report PDUs
0 Wrong Digest Report PDUs
0 Decryption Error Report PDUs


Get-request PDUs + Get-next PDUs /= Get-response PDUs
42468880 + 91148753 =(133617633) /= 133675965

Get Response are greater by 58332 PDUs.
Please assist in solving this query !!!
