Yes, the server running Kosmo have more applications running on it. I needed
to limit java memory use, so I applied the xms and xmx command line options
to set it to 500 and 800, having noticed at first glance that Kosmo in my
application wouldn't need more than that to work fine, as you can see it's
not a really big thing. The database server is running on another computer
( Postgresql on a linux system ).

Yes, Mr Jukka.  I began worrying about memory usage of Kosmo when I noticed
it were going slower after some time of use.

I'll update kosmo to a newer versiĆ³n and try again.

Thanks Sergio and Jukka,  a lot for helping,
