OK, I didn't know that was a surprise. There are about 600 stats dump lines
in between.

you could probably generate a test case with relatively little data,
or maybe a lot of easily-created dummy data. However stripping it down
might require more insight into the nature of the bug than we have at
this point.

I did a test in a small area (which is the street network in a county) before and it worked without crashing the
server.In that test there were about 600 records (or addresses) to be processed while in the current case there are
about12K records. Another difference is that the current case uses a larger base relation (the one I mentioned my
previousemail) that covers a whole state. I'm not sure whether it is the amount of records to be processed or the size
ofbase relation that causes the crash.
