Looks like the FTP server implementation is broken. >[/home/zope/Python-2.4.4/lib/python2.4/asyncore.py|read|69] >[/home/zope/Python-2.4.4/lib/python2.4/asyncore.py|handle_read_event|391] >[/home/zope/Python-2.4.4/lib/python2.4/asynchat.py|handle_read|89] >[/home/zope/Python-2.4.4/lib/python2.4/asyncore.py|recv|347] >[/home/zope/Python-2.4.4/lib/python2.4/asynchat.py|handle_close|156] >[/home/zope/instances/www.emss.co.za/parts/zope2/lib/python/ZServer/medusa/ftp_server.py|close|181] > >[/home/zope/instances/www.emss.co.za/parts/zope2/lib/python/ZServer/medusa/ftp_server.py|close|906] > >[/home/zope/Python-2.4.4/lib/python2.4/asyncore.py|close|360] >[/home/zope/Python-2.4.4/lib/python2.4/asyncore.py|del_channel|248] >[/home/zope/Python-2.4.4/lib/python2.4/asyncore.py|__getattr__|366]) The problem is probably in "...ZServer/medusa/ftp_server.py|close". I expect that the order of things is not right or that something redundant is done. A ZServer puts a channel object into 'asyncore's service map. Each element in this map must have a 'fileno' method that tells 'asyncore' which file number is associated. The exception above happens during closing the channel. "ftp_server.close" probably calls the channel's 'close' which calls 'del_channel' which accesses an object that meanwhile in "None" while it is still expected to be an object with a '_fileno' attribute. -- Dieter _______________________________________________ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
