Hello,
I dont' understand one point: - the gdchart cause one request to hang, good. But this should not froze the zserver, usually there are several threads running.
As I understand, the zserver should froze when you have sended N requests which get stuck in the gdchat lib. N being the number of threads configured in Z2.py. Was it like this??
that really depends on the library, if you make a call into a c library without doing the proper PY_ALLOW_THREADS incantations than you can possibly hang the interpreter, for the length of the call to c. however just about every well written c module does do the proper thing, i'm not familiar with the gd lib stuff, so i can't comment on it. and of course if the library itself isn't thread safe there are other possible complications. kapil

Hi,
Ok, we( my SysAdmin and i ) have found the problem of hanging. After hours of searching in the python Sources of all the Products which are involved we have nothing found. At this point my SysAdmin has the idea to trace the python processes with gdb. After this we could see that Zope was running somewhare in the gdchart.so module. After an update of the gdchart.so the problem doesn't occur anymore. I doesn't know enough to work with gdb, but if my SysAdmin were not able to work with gdb so very well, i never have found the point were Zope runs into another universe :)
thanks as
