I am getting a "FAIL" message back when executing pgr_createTopology on a particular table, but the reason is not obvious. Is there any way to know precisely why the function is failing? Perhaps some sort of pgRouting log?

There should be a message for each failure, but eventually one (or more) have been forgotten?

You could try do debug the problem by modifying the pgr_createTopology function, for example by adding more intermediate output to the pgsql function.

There is no pgRouting log, except the messages generated with raise notice.
