Hello, What are the reserved id in Zope?? For example: I can not add an 'icon' document in my '/test/' folder. That's annoying during massive documentation import from the filesystem. So: 1) has someone the complete list of 'reserved' id 2) is there a way to get arround it. Thanks A, I have another question, but a difficult one this time, it's about zserver/medusa: I have the last zope running on linux x86, behind apache using pcgi. The access with pcgi is much slower than with zserver, so I would prefer to use zserver. But I am asking myself: - has someone a zserver diagram?? or a (clear) explanation of who it works. - which event trigger the thread creation: if I specify -t 10, I think zserver start with less threads. Are they created 'if needed' (when all other threads are busy) ?? where is the corresponding code. - what are zombies channel? anyway when are channel created? for every request?? - are the zombies channels killed? (there is a timeout of 100 mins it seams). BUT my last experimentation (~one year ago) was making me thinking the cleaning point is never reached. - is it possible to 'reserve' one http thread to management purpose? to be able to restart the zserver in case of hang?? ( I remind you that I am the proud creator of a very stupid method able to froze the zserver, see mailing link age ago :-) What is the percentage of productions sites using directly zserver??? Gilles
