Did you ever change the tx timestamp timeout value? It may be the case that you had increased that value before, (If you had not I would be very surprised...) You may try increasing the poll timeout to 5 or so and see if that helps the issue.) It is likely that you are simply not waiting long enough. That is a known issue with some Intel cards regarding how the Tx timestamp is returned and there is nothing that the driver can do to decrease the time required to get the timestamp. :( - Jake ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite!
