Not a reliable test case, unfortunately...

The place I observed it most frequently was about a year ago, the NYC 
data used on the front page of geoserver.org. (nyc_nj_bg layer group 
served by /geoserver on artois.openplans.org).

Sometimes it will simply render a metatile without the roads. Delete the 
cache and it renders it fine the next time. We scoured the log files 
several times, did not find anything.

I think Ivan reported something similar with the OSM layer last week. I 
did not investigate before installing JAI / wiping logs though.
