Hey Robie,

Thanks for the reply.  I had a gut feeling that some of you might know a
similar issue.  Indeed, it seems like they're related; during my
investigations I also noticed the TimeoutSec parameter in the service
file, and thought that the next step of the investigation could start
there.

I left a question to the reporter asking whether they have a big
database.  If they do, then I (or someone) can try to populate the test
database with dummy entries and try to replicate the scenario.  Let's
see.

Thanks,
