I too have noticed problems with set requests on the stack when attempting
to change snmpv3 passwords using the USM mib, RFC 3414...

Hi,

     I have been using WestHawk SNMP API for few years now.     Currently I
am facing a peculiar packet loss issue.

     I have a progream that sends a series of set requests to an SNMP
device. All the set-requests work perfectly in standalone. When executed one
after another, they execute successfully 5 out of six times in the other
instance I get a Timeout exception in a Random place.

When I attempted to trace the packets with Wireshark (assuming that it is a
device problem) I noticed that the response for the set request was properly
received by the machine immediately, but It was not captured by the
particular Westhawk session.

I am not sure how to fine tune the WestHawk API to prevent it from dropping
any packets. Thanks, Kevin _______________________________________________
