Hi, I am running a fairly high traffic Zope server where people occassionly ftp files in and out of the server. Approximately once per week, the zope process will go to using 99%CPU and stay like that untill it is restarted. The error shown in the stupid log file is: 2002-03-06T01:22:41 ERROR(200) ZServer uncaptured python exception, closing channel <zope_ftp_channel connected 202.129.84.50:64011 at 8ac4ecc> (exceptions.RuntimeError:maximum recursion depth exceeded [/usr/local/lib/python2.1/asyncore.py|poll|104] [/usr/local/lib/python2.1/asyncore.py|handle_write_event|393] [/usr/local/zope/Zope-2.4.3-src/ZServer/medusa/asynchat.py|handle_write|147] [/usr/local/zope/Zope-2.4.3-src/ZServer/medusa/asynchat.py|initiate_send|209] [/usr/local/zope/Zope-2.4.3-src/ZServer/medusa/asynchat.py|refill_buffer|190] [/usr/local/zope/Zope-2.4.3-src/ZServer/medusa/ftp_server.py|close|179] [/usr/local/zope/Zope-2.4.3-src/ZServer/medusa/ftp_server.py|close|903] [/usr/local/lib/python2.1/asyncore.py|close|355] [/usr/local/lib/python2.1/asyncore.py|del_channel|241] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] .... and so on... Line 361 in asyncore.py is: 358 # cheap inheritance, used to pass all other attribute 359 # references to the underlying socket object. 360 def __getattr__ (self, attr): 361 return getattr (self.socket, attr) It hints to me that it is some sort of ftp server error that is causing the problem. I have looked into it, but most of it is over my head and I was hoping somebody could help. I have tried to reproduce the error, but without success. The server is: FreeBSD4.3 Zope 2.4.3 (from src) python 2.1.2 terry -- Terry Kerr (terry@bizarsoftware.com.au) Chief Technical Officer Bizar Software Pty Ltd (www.bizarsoftware.com.au) +61 3 9530 9182
