... I compiled Python 2.4.4 on AIX 5.3, with cc_r compiler, installed Zope-2.9.8and Plone-2.5.1.
Everything seems work well, excepted when I call Plone on the browser or click on the "view tab" inside one Plone site at the ZMI. When I do this, I get a "Segmentation fault" on the server.
Looks very much like a C runtime stack overflow.
... I found this text in at Zope-2.9/doc/PLATFORMS/AIX.txt :
"from Wolfgang Roesner (reporting segfaults and a fix)
The default stack size for a pthread on AIX (at least in my configuration) is 96kB. On Solaris it's 1M. As soon as I explicitly set the initial stack size to 1M the problem went away and it appears as if Zope is up and running.
Unfortunately I really had to change "thread_pthread.h" in Python which obviously is not a nice thing to do as I now have a need for my own private version of Python. But at least I have a running version of Zope on AIX."
Is this really something to try?
Definitely. Almost surely, you see precisely this problem (C runtime stack too small). -- Dieter
