Yes, this is very well known problem. Please look at kern/5890 (by Remy
Nonnenmacher). In our environment we had to use suggested patch to use
FreeBSD as NFS server and Solaris NFS clients (v3).

There was another discussion about it in the middle of November 1998
(initiated by me and followed by helpful answer from Remy) on -current
mailing list.

As I see, the kern/5890 is stopped with following question:

  Hi Remy, (Sat Apr 25 22:21:50 PDT 1998)
  Can you retest this bug?  Peter made many changes to sys/nfs/nfs_serv.c
  over the summer.  From the commit logs, I suspect it might be fixed.

I can answer: Yes, the problem is still here (3.2-RELEASE and -CURRENT).
I am closely observing cvs logs and looking for fix because this is
unpleasant bug for us - but latest fix for readdirplus() still
didn't help...

(What about new kernel compilation option SOLARIS_NFSV3 or
new sysctl variable? :-)
