ubc_uiomove: error=14

Hi!

I recently booted a -current kernel from Oct 27th sources on a
Sun Enterprise 450 system.  It seems much more stable than the
9.1_STABLE kernel it ran previously, in particular under heavy
load on all its 4 CPUs.

However, I got the following message (only once so far) on the
console:

[ 70050.869615] ubc_uiomove: error=14

Should I worry?
