Subject: What to do with this message (2.6.30.1) ?

Hello all,

first day of using 2.6.30.1 on a box that mostly accepts rsync connections 
revealed this message. This is in fact not the only one of this type. Quite
a lot from other processes follow. What can I do to prevent that? Is that
a kind of a bug? 
I did not experience that on a box with the same job using tg3 instead of
e1000e.
