>Hi everybody,

>My application running as an NT service opens - with FOPEN(cFile), analyzes - with FGETS(nHandle, 1000), and closes - with FCLOSE(nHandle), a big text file (of some 2 million rows). During analysis it performs a hard check of data consistency (many IF...ENDIF's), stores important things in a table, and closes it, then sleeps waiting for another wake-up. I noticed that during fgetting rows the RAM usage increases and is not released even after FCLOSE (in this way I loose some 500MB and more). I have to exit the program to give out all memory. Any hints or suggestions? Thanks in advance.

Przemek, just an idea ...

Get the task-manager of NT up front (right-click on taskbar) and click the tab which shows the cpu-useage. It shows the memoy-used too. Just let the app running as usual, and see whether it frees the memory by itself. I mean, what you state is my experience too (on very different operations) but after a while NT frees up the memory. So the only thing I am saying : is it a real memory leak or does it just appear to ?
Note : your "runs as a service" I'm not experienced with at all.
