What's updating the DB file and can you modify it to un/lock the file
while it's making updates?

In days past, I built some tools for working on DB files for just this
reason.

The ISP had a large number of hosted domains and consequently we had
lots of alias files that were being updated frequently. At the start,
we saw problems with rebuilding a "live" DB file, so tools were
created that locked the files before updating them and then unlocked
them.

I'm now using the same set of tools for a new Exim setup at the
current job and haven't had a problem yet.
