I've set up a test script that starts and stops my host-end application, and so far have about 500 TCP/IP open/close cycles without problems. I haven't been printing MBUF counters, but I haven't seen any panics or anything else odd. After I let this run for a while longer, I might have to try it with the program from the test suite. Is the source for the eCos port of the goahead publically available? Sometime in the next few weeks adding an HTTP server is going to end up at the top of my list of things to do. -- Grant Edwards grante@visi.com
