wrong report of memory for multithreaded apps #2

We are using colmet on our cluster and i have noticed a problem with multi-threaded applications:

colmet reports a wrong amount of memory usage: if my apps is using 3.6 GBytes and have 16 threads, colmet reports almost 50GB , it looks like it is multiplying the memory used by the application by the number of threads, but this is wrong (confirmed by using 'top' and 'free').
