Serious Memory Leak

There is a very serious memory leak in Version 5.1.  I am reading a large (900,000 rows) csv file in.  The system monitor shows memory usage slowly increasing, as expected. But when the process finishes, and a new process is started, the memory usage starts at the same level where it was when the first process ended-  the  2nd process then crashes due to lack of memory!

I have tested this with the Windows performance monitor as well- which confirmed that the memory was not being released when the pocess ended. 

I am using the "Free Memory" operator- which seems to have no effect.

The only way to run the 2nd process is to restart Rapid Miner!

Please correct this error as soon as possible!

Thanks!
