--- Comment #8 from Richard Mortimer <richm+kde at oldelvet.org.uk> ---
I'm concerned that increasing the max packet size is only hiding the problem
and not curing the real problem. A similar error is also reported for SQLite so
that would need an equivalent "fix".

Has anyone worked out what the underlying cause of the problem is? I think it
would be hasty to apply a fix that papers over the issue because it will become
a harder problem to solve later when even bigger datasets are involved.

The fact that it occurs later with bigger buffer sizes makes me think that the
code is trying add everything in one big statement rather than adding in
smaller chunks. I'm sure that there will be a performance benefit in adding a
number of items at a time but it would be good to limit that to a reasonable
value (will require a bit of experimentation) to ensure that it does not break
size limits etc.
