Just in case anybody is actually reading, I managed to get snoop loging NFS traffic, while an ESTALE occured:

Filehandle old: FH=4F4F in line 159800 the server actually discovers an old FH and assigns a new FH line (159802: FH=56B5) which obviously does not match the old FH. Which appears to be the reason for ESTALE, if not misinterpreted. Since we are talking about the same file, I really do wonder why ?? What happens if at the same time an volatile FH expires as the NFS server goes down ?? Hoping that a someone knowledgable shows up to enlighten me and put it straight Oliver This message posted from opensolaris.org
