as the memory is even gone after apache with mod_perl has been stopped, I do not think that this really helps. I do know that the kernel should recover all the memory when processes stop even if these did not free the memory, thus it seems that the kernel is responsible for that behaviour. However, I have seen these strange things on several kernels (2.4, 2.6) from different distributions (Redhat, SuSE) so that I can not believe that this is in fact a kernel problem. Any more ideas? Thanks in advance, Andreas
