This is not a TileCache crash, this is a GeoServer crash. Sounds like
you ran it out of RAM. I have no idea bout anything about GeoServer, but
all TileCache does is talk through WMS, so there's nothing it's doing
here that should be able to kill Java in any special way.

The GeoServer list is a good place to start, but you probably also ant
to upgrae to the lastest version of GeoServver if your' enot already on
