ok so v.distance is taking a very long time.


can you try with "v.what.vect --vebose" ? that should give some more
messages from v.distance instead of just 100% 100% 100%.

also, you can turn on the debug messages:

g.gisenv set="DEBUG=1"

turn it up to 2,3,.. to get more messages. set it back to 0 to turn them
off.

I see one in v.distance "G_debug(3, "SQL: %s", db_get_string(&stmt));"

maybe more DB troubles?
