samba - Feb 2003 - too much work?

Hi,

Since I managed to get Samba working I've noticed that when I copy large
files, or lots of little ones ( about 4Gbs Worth), I get a message on
the Linux box saying;

Eth0: too much work at interrupt, intrstatus=0x0040

Now so far nothing has gone wrong, i.e. corrupt files etc
Is this something I should be worried about?
If not how do I stop the message from appearing? 
If it is a problem how do I go about fixing it?

I'm running RH8, Samba 2.2.7a



Thanks

Roland
