We are developing a real time application. The function of this
application is to create an event journal that has 3 levels :

1. The first is a TClientDataSet with 10000 lines maximum. This is a
table in memory.
2. The second is an InterBase table with 150000 lines maximum.
3. The third is an unlimited Interbase table in a server that saves all
the installation journal lines.

The first and the second levels are circular tables.

This application cans be installed in many machines over a network.

We have a problem with the first level, the application begins to take
and take the memory until the machine is saturated. but there is
something odd, there are machines where the application is stable.

In this application we don�t use new or malloc sentences, we don�t
create objects in runtime, only we write in the TClientDateSet and in
the Interbase tables.

Can a TClientDataSet take the memory when we write and rewrite into ?
don�t forget that this one is a circular table.


Thank you

PD: I saw that someone has the same problem (april 11: Memory usage
increase using TClientDataSet as a local temporary dataset), could BTeam
answer us?
