Hello, 

I have a problem : memory disappears (leaks) during calculation,

code:
===============================
ClearAll["`*"]; 
$HistoryLength = 0
n = 5; 
Do[bound = Table[{wsk, Integrate[Sin[p], {p, 0, 3}]}, {wsk, 1, 100}];
 ClearAll[bound]; 
 Print[MemoryInUse[]]
,{st, 1, n}]; 
=================================
output:
----------------------------------
24971664

25168576

25365240

25593976

25789224
----------------------------------

When I used simple calling function ( Sin[] instead of Integrate[Sin[]]
this effect didn't occure.
I tried $HistoryLength = 0, ClearAll[bound] and also with no effects

In my real calculation I used more complicated function . I tried to obtain
tables of numerical intergrated functions and I was saving it step by step to the file.

After many steps my all memory leaked and server crashed (  48 GB RAM)
The table "bound" contained only 50 numerical results of integration per one step

(system Linux Scietific , Fedora, Ubuntu)


Have you any ideas ?

With Best Regards, Olaf
