My guess would be that scriptindex is indeed flushing, and that what
is happening when you get the blank page is indeed that the apache
timeout is reached.

The reason this only happens during flushing is probably that
scriptindex is doing a lot of I/O then which means that omega is
competing for I/O bandwidth.

And the reason you only see this with the date range enabled is probably
that the date range filtered query requires quite a lot more I/O than
the query without the date filter.
