Hallo,

I'm a FreeBSD user for years with machines in production since V2.X.
At the moment I have a really strange problem in our environment.

  - NetApp Cluster NFS file server
  - HPUX-11, Solaris-8, FreeBSD-4.11 Clients

  - 60000 Virus/Spam scans a day, spread over 5 different FreeBSD Machine=
s,
    two different hardware bases, 1GBit Network

A problem occurs with the Sophos PMX (PureMessage Anti-Spam/Anti-Virus)
Application. 1-3 times a day the following happens:

  - pmx_log:3 2005-06-23T12:26:58 [36968,milter] pmx_file(): =

    Can't append message info to '/usr/local/pmx4/var/qdir/tmp/1119522418=
-36968:135299072-ZN0IIE00EX1IKSAE.00-738-vscan1.hrz.uni-bielefeld.de': Ba=
d file descriptor at /usr/local/pmx4/lib/site_perl/5.6.1/PureMessage/Mess=
ageFile.pm line 124.

  - /usr/local/pmx4/var is located on the NetApp Filer (NFSv3)

  - Line 124 referenced above looks like (close($f)):

sub make {
    my $class =3D shift;
    my $fname =3D shift;
    my $minfo =3D @_ =3D=3D 1 ? shift : do {
        require PureMessage::MessageInfo;
        PureMessage::MessageInfo->new(@_);
    };
    open(my $f, ">>", $fname) || die "Can't append to '$fname': $!\n";
    print $f _minfo_block($minfo);
    close($f) || die "Can't append message info to '$fname': $!";
    1;
}

  - BUT: The message-info is absolutely correct appended!

This does not occur if I move /usr/local/pmx4/var on a local disk.

No errors in any logfile!

No problems with other Servers!

Any ideas? Is there a kernel NFS or interoperability problem with the =

NetApp Filer.

How can I debug this on FreeBSD?

Best regards

Lars
