Ram -

We are seeing a lot of OOSEQ packets. It it looking to us like when this happens our processing load / cpu utilization is increasing significantly. Have you observed anything like this?

If true, this seems to be having a cascading effect where the application does not get enough cpu time to drain data from the API quickly enough -- which seems to be resulting in us overflowing the mailbox between the stack and the API (we are using the sockets API). This looks like where we are losing pbufs. At least it is the first place we have found.
