sshd sylog '/proc/self/oom_score_adj to 0' since upgrading to natty

[Adam Funk]

I upgraded two machines with sshd on them from maverick to natty.  On
only one of them, I get a lot of this

#v+
sshd[7967]: Set /proc/self/oom_score_adj to 0
#v-

in my logcheck output (even when no ssh connections are being made).
Does it mean anything, or should I add it to the local-ignore rules?

Thanks,
Adam
