Hi Folks,
I'm getting the error message below on the 6509 :
SNMP-3-INPUT_QFULL_ERR: Packet dropped due to input
queue full
12-03-2008 02:56 AM
%SNMP-3-INPUT_QFULL_ERR : Packet dropped due to input queue full
Explanation Snmp packet dropped due to input queue full error.
Recommended Action Use the command show snmp to see the number of packets dropped. Stop any SNMP access to the device until the error condition is recovered.
Investigate if it could be a possible bug of your specific IOS (please let me know the IOS release).

You have an IOS bug: CSCsk27147
You need to upgrade it.

I forgot more details :)
CSCsk27147 Bug Details
SNMP stops responding while polling from CISCO-MEMORYPOOL-MIB
Symptoms: The following SNMP is incorrectly generated:
"%SNMP-3-INPUT_QFULL_ERR: Packet dropped due to input queue full
This issue is affecting the CISCO-MEMORYPOOL-MIB instead.
Conditions: Occurs on a Cisco 2600 series router running Cisco IOS Release 12.4(11)T3. The router
keeps dropping SNMP packets. The log shows that the packets are dropped because of the input queue
beeing full. Although the utilization is sometimes high, this could not be the root cause, as the router
keeps dropping packets regardles of the current utilization. Also, the snmp process takes 5-20% of the
CPU load.
Workaround: Exclude ciscoMemoryPoolMIB from your query with the following commands:
snmp-server view public-view iso included
snmp-server view public-view ciscoMemoryPoolMIB excluded
Apply this view to the RW community string. This view will exclude only ciscoMemoryPoolMib, all other
MIBs will be available.
My advice: upgrade to 12.2(33)SXH4, the last release of your train.

Andrea,
I'm still getting the error messages even after excluding the ciscoMemomoryPoolMib, see commands below,
snmp-server view public-view iso included
snmp-server view public-view ciscoMemoryPoolMIB excluded
snmp-server community ********** RO
snmp-server community ********** view public-view RW
The other thing:
The SNMP Engine using about 30% of cpu.
I will upgrade to latest ios.
Thanks a lot Andrea, much appreciated.
