But it displays the children hierarchy without an indication what children are full blown processes and what are threads. Nevertheless, your message was good for me. I knew, that there is a ps option that shows the children hierarchy, but I did never look at it. It was quite impressive, when I did after I got your response.

[Zope] Memory problems
Hi, Since a few days I'm experiencing some response problems on my zope site. At some moments calling a page goes very fast a few seconds later, recalling this page takes very long! At the end, every page takes long time, if they ever appear If I use a simple memory checker program, then I see that memory leaks away (memory goes from 48Mfree to 41M in 15min!! and eventially it ends at a few thousands K) However, I've no idea if it is comming from Zope 2.2.5 or from my database adapter in zope, or from somewhere else Is there a good way to check memory leaks and to pinpoint them? If I ask to show me the processes on my Linux box, I see the following related ones : /usr/local/zope/bin/python /usr/local/zope/z2.py -Z /home/httpd/zope/var/zProcess.pid (root) /usr/local/zope/bin/python /usr/local/zope/z2.py -Z /home/httpd/zope/var/zProcess.pid (nobody) /usr/local/zope/bin/python /usr/local/zope/z2.py -Z /home/httpd/zope/var/zProcess.pid (nobody) /usr/local/zope/bin/python /usr/local/zope/z2.py -Z /home/httpd/zope/var/zProcess.pid (nobody) /usr/local/zope/bin/python /usr/local/zope/z2.py -Z /home/httpd/zope/var/zProcess.pid (nobody) /usr/local/zope/bin/python /usr/local/zope/z2.py -Z /home/httpd/zope/var/zProcess.pid (nobody) /usr/local/zope/bin/python /usr/local/zope/z2.py -Z /home/httpd/zope/var/zProcess.pid (nobody) gds_inet_server # Interbase Database Remote Server (root) gds_inet_server # Interbase Database Remote Server (root) Is it normal that zope opens so much processes?
