othane:

Possibly, but to do so, you'd need to know where that memory is--i.e., what variables are holding it. Then you could clear the data. Perhaps simply deleting and rebuilding $svm may be enough to clear the memory for you. But without knowing what the subroutine is doing, I couldn't offer you more help than that.
