getting lots of kernel nfs: server not responding

Hello
 
I have two boxes. One is the NFS server and one is the client.
 
They are very busy web servers.
 
i keep getting these errors on my console and in my message file
May  3 12:44:11 krusty kernel: nfs: server local.flanders not responding, still trying
May  3 12:44:15 krusty kernel: nfs: server local.flanders OK

these two boxes each have a GIGaBit ethernet card and a crossover cable connecting each other and it is only used for NFS.

All other network functions use the other nics

Stats are below, I am currently running 49 nfsd's

Thanks for any suggestions
