Sporadical NFS errors with NetApp backend

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 Machines,
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': Bad file descriptor at /usr/local/pmx4/lib/site_perl/5.6.1/PureMessage/MessageFile.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 = shift;
my $fname = shift;
my $minfo = @_ == 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
