Hello,
we use the TClientDataSets in an service application.
While running, we noticed a increasing memory for this service appliction.
We found out, that the increasing memory was allocated form the
TClientDataSets / Midas.dll.
To check this I made a small testapplication with datamodule.
The datamodule contains 4 ojects, SQLConnection, SQLDataSet,
DataSetProvider, ClientDataSet.
The app has 2 timer, one with 100msec intervall to simulate changes in the
dataset,
and one with 10Sec to call ApplayUpdates for writing the changes into the
database.
Please see the example code.

We tested a lot in the last days, but we have allways increasing memory.
I hope somebody have an idea for this problem.

Thanks.

void __fastcall TForm1::Timer100mSec(TObject *Sender)
{
//  OnTimer Event Timerintervall 100mSec.
  TClientDataSet *CDS;
  CDS = DataModule_Test->ClientDataSet1;

  CDS->First();
  CDS->Edit();

  int nCopyCnt = CDS->FieldByName("COPIES_PRINT")->AsInteger;
  CDS->FieldByName("COPIES_PRINT")->AsInteger = nCopyCnt += 1;

  AnsiString asMsg;
  asMsg = IntToStr(nCounter) + " ";
  asMsg += asMsg.StringOfChar('A', 1000);
  CDS->FieldByName("BUFFER")->AsString = asMsg;

  CDS->Post();
}

void __fastcall TForm1::Timer10Sec(TObject *Sender)
{
// OnTimer Event Timerintervall 10Sec.
  TClientDataSet *CDS;
  CDS = DataModule_Test->ClientDataSet1;
  CDS->ApplyUpdates(-1);
