I have a Sage server running on a Dell PowerEdge, launched using the screen
command. Some recent Sage event (that I haven't had a chance to
investigate yet) filled the filesystem with log messages. When I move the
log file out of the way and attempt to restart Sage, I get the following
traceback with no other error message:
$ sage-notebook
Traceback (most recent call last):

The sage_notebook script I use to launch the Sage 6.3 server is:
#!/usr/bin/env /usr/local/bin/sage
#
from sage.all import notebook
notebook(interface = '', port = 34567, secure = True, accounts = True,
automatic_login = False,
timeout = 720000,
directory = '/var/www/sage/sage_notebook.sagenb',
server_pool = 3 * ['sage@localhost'])
Can someone tell me what is failing and where to look to debug this?
TIA.
