It sounds like the space is allocated but unused pages. Unless you have messed with some kernel memory manager settings, unused virtual pages consume no physical RAM. You could confirm this by using ps to check how much RSS is actually used, compared to VSZ allocated (VSZ - RSS shouldn't include any actual data unless your system is actively swapping stuff to disk). If it is just unsued pages it's not a problem.
Thanks. I've looked at this, and can confirm that the reported VSZ and RSS are almost the same (120MB and 116MB). I think this means that the observed memory usage is real. Tim
