Public bug reported:
Binary package hint: trac
My web server hangs up every few days since I upgraded it to lucid. One
error I see in the logs is this trac bug.
Line 464 of /usr/lib/python2.6/dist-packages/trac/web/api.py references
the socket module, in Request.write:
except (IOError, socket.error), e:
The file does not import the socket module, so I get a traceback:

A simple "import socket" near the top of the file should fix this.
I have yet to see whether this fix stops the hangups. The hangups seem
to be related to trac fcgi processes spinning forever on a lock.
Sometimes I catch them merely using up all CPU. I can only guess about
the times when I can no longer get into the server; the server still
runs to some extent and reportedly uses all available CPU time when that
happens.
