I'll try. I think I should only need the geolite data to cause the problem
and I can share that publicly. So far the problem seems to be happening
consistently. I'll work on this at the office, but probably won't get it
done until the afternoon.
If I have a substantial database dump file to provide for reproducing this
do you prefer it on a web server somewhere? I expect that mailing very
large attachments to the lists is a bad idea.
