Hi
I am using T2 nihtly build from 22.04.2009.
I am opening a lot of T1 workflows, executing some of them and closing
them, so that i have only one opened at a time.
After ~50 workflows the memory usage goes to above 330Mb, The CPU usage
goes to >90% and I get following error (see below). It must be some kind
of memory leak because when I close the workbench and open it once more,
everything goes all right.
