Hello, I have been trying to run Zope/CMF on a HP9000/800 machine (rp5430, HP-UX 11.00) for several full days, with no luck. I got advice from various people, but the problem is always the same : after a few steps in the creation process of a CMF site, python goes in an infinite loop, using 100% of the cpu it is on. The log file doesn't indicate something special. It just stops being fed. The same happens simply in the ZMI if I want to select the view of the error_log object. The feedback I got mentioned a classical threading problem. I had first compiled python with gcc, and as people said it was its fault, I switched to c89+aCC (from HP), and tweaked the python Makefile a lot (including -D_REENTRANT and -lpthread flags in various places). I also patched my system with a cumulative patch for libpthread and a patch for c89 found in the HP database by typing "Python" in their search engine. All this changed *nothing* : the problem is the same in every config I tried. So my question is very simple : has someone been able to run Zope (and CMF) on this (or a similar) platform ? I feel very disappointed having lost all that time for nothing, but anyway, the server is here and I am seen as the "bad guy" when I tell the managers that we can't run our brand new intranet (powered by Zope/CMF) on (so expensive) machine... My suggestion on buying a PC has not made them smile at all. Many thanks in advance for any help, -- Damien Wyart
