Maybe the just reported feature is a solution to this bug.

maybe a more detailed analysis than `wc` & `grep`, i.e., manually inspect
the output, might shed some light on this ...

ps: haven't managed to analyze/fix the bug in ds_link() of module mkey
(cf.,
[ 2038906 ] XML attribute generation
http://sourceforge.net/tracker/index.php?func=detail&aid=2038906&group_id=56967&atid=482468
, yet, but we will look into this as soon as time permits...

Thanks.

The problem might be cause by problems in the element construction in the
Algebra back-end as, e.g., reported in
[ 2038906 ] XML attribute generation
http://sourceforge.net/tracker/index.php?func=detail&aid=2038906&group_id=56967&atid=482468

Could you please try whether the old "milprint_summer" back-end (`mclient
-lx -g`) shows the same (or other) problems, or whether is works fine?

In any case, I don't expect this to be in any way related to how/when
results are emitted, nor that any change in that would "solve" this bug
...

And to be even more verbose:
[EMAIL PROTECTED] /var/tmp $ grep -c "<node " planet-nl-latest.osm
5689472

Is my flower broken?

I expect the output file to have 5689472 lines. And the output file
doesn't have more lines than 4478?

http://hypercube.telascience.org/planet/planet-nl-080823.osm.gz is the
source input file. It has been added with update support and 10% overhead.
(I'm happy to give a login so you don't have to redo this process) The
server has been compiled with --enable-optimise.

And the script is as simple as the above.

Could you please be a bit more elaborate on what the bug is that you
report?

Please also (try to) provide all the information (incl. scripts and data,
or at least access/references to them) that is required to reproduce the
bug?

Thanks!
