Hi,
Yes, I can repeat the error. At one certain zoom level requests to get some tiles always fail. The error at Geotools dev level is:
16 touko 11:25:35 ERROR [org.geowebcache.GeoWebCacheDispatcher] - Problem communicating with GeoServ
er http://localhost:8080/geoserver/gwc/service/wms
Here comes all that appears into the log when panning a bit at that zoom level. It is quite a lot, normal Geoserver users can stop reading here.
