[csw-maintainers] close on nfs mounted file retruns EINVAL on i386

[Carsten Grzemba]

Hi,

i tried to build ocaml. It builds without any problems on Sparc on our buildfarm. But it raise a annoying error on i386:

cgrzemba at unstable10x:~/opencsw/ocaml/trunk/work/solaris10-i386/build-isa-pentium_pro/ocaml-3.12.1$ boot/ocamlrun boot/ocamllex parsing/linenum.mll ### OCaml runtime: debug mode ###

Fatal error: exception Sys_error("Invalid argument")

The invalid argument caused by a close of a file on NFS mounted FS. It works if I try to write the output to local.

It is a known problem:

The are is a work around provided which ignores the EINVAL return value from close.
Has anybody else seen such problems with NFS.
