If you can get the GatorBox to restrict it's requests to 4Kb you - should be OK. - - -- - Dan Ehrlich /Voice: +1 814 863 1142/FAX: +1 814 865 3176 Steve has already indicated the solution: NFS_MAXDATA should be 8Kb. We had the same problems as Steve and with the new kernel everything works fine. Werner H.P.
