We're using tcpdump to try to diagnose an NFS performance problem.
We're seeing a lot of these :
16:01:19.890794 IP nfs_server.nfs > client_46.1205729087: reply ERR 1448
16:01:19.890831 IP nfs_server.nfs > client_46.3664003007: reply ERR 1448
That seems to be an RPC error, handled in print-nfs.c. That part of the code
has changed in tcpdump-3.9.7, which we installed, and now gives :
16:01:19.890794 IP nfs_server.nfs > client_46.1205729087: reply Unknown rpc
response code=3128327487 1448
16:01:19.890831 IP nfs_server.nfs > client_46.3664003007: reply Unknown rpc
response code=910276799 1448
I don't understand what's happening here. Is it something wrong with our NFS
setup, or I'm misunderstanding the tcpdump output ?
Not sure if that would matter but, the server is a solaris 10, linux fedora
clients, NFSv3 over TCP.
Any pointers welcome !
