A file can be opened, written to for a while, :and then -- at a semi-random moment -- the log will drop across the road? :Ouch... : :Thanks a lot to all concerned for helping solve this problem. Yours, : : -mi I consider it a bug. I think the only way to reliably fix the problem is to give the client the ability to specify the uid to issue RPCs with in the NFS mount command, to match what the export does. -Matt Matthew Dillon <dillon@backplane.com>
