The same happens to me against a linux 2.0.20 Server when i'm using the Solid Database server. The database runs on 2.0.20 server, the client on a 2.1.16 box. tcpdump shows, that the client is transmitting TCP ACKS as fast as possible. The server is so busy receiving the ACK's that the NFS part of this server disappears from the net for short times. If anybody wants a can provide a tcpdump log. This is absolute reproducable. --- g.a.m.s. edv dienstleistungen gmbh finger mla@murmel.gams.at for PGP key <http://www.gams.at/~mla>
