This was addressed off list. For the benefit of the list - this is an
erroneously reported error. What's really happening is a timeout when
zigGIS makes the initial connection to the DB as it queries all the
available tables.
We'll need to fix the timeout issue by either making it configurable
or setting it to a very large value. In the mean time, a work-around
is splitting your datasets up into multiple databases. Twenty tables
per database should work well.
