It's messaged issued by perl (for some not-yet-investigated 
reason).  If you don't need embedded perl - just compile nginx 
without it.

Am I right in the assumption that this happens on restart?  If 
yes, there were some reports that fixing init script to wait for 
nginx to stop before starting a new copy (or at least adding a 
sleep 1 between stop and start in restart function) helps.  Or 
better - you may use reload instead (since there are no real 
reason to restart nginx, reload usually sufficient and doesn't 
loose any single request).
