Hi,
I seem to have found another problem a bit worse than the one you mention
Alan, my Linux client is 2.2.0-pre4 and I have a Solaris 2.6 + recommended
patches Sun workstation server,
I do a TCP mount
mount -t nfs -o tcp,nolock oak:/foo /foo
I then do a
cd /foo ; find .
It works for a while and then the process hangs in rpc_execute,
I've switched on rpc_debug, and I think I have tracked down a problem when
the server sends me a RPC packet bigger than 1440,
I've attached two files 205.txt and 206.txt these are two RPC traces one
after the other, the 205 seems to succeed (it does the same as all the
previous ones, but the 206 with the 3556 bytes cause problems, the system
keeps trying to do some sort of resend on it but never gets a reply ..
I'm going to have a dig around and see if I can see what might be wrong,
Dave.
