The [http://www-users.cs.umn.edu/~jansen/temp/20120822-tor-infologs.tar.xz
new logs are here].
I reduced it from 120 GB to 4.5 GB by filtering out lines containing:
'torrent client encountered a non-asynch-io error'. The P2P plug-in code
doesn't differentiate that error other than that its not `EAGAIN` and its
not coming from a `send` or `recv` call. (Apparently, it also doesn't
rate-limit its reconnection attempts :P)
I suspect its coming from the attempted SOCKS connection because our file-
download plug-in has similar problems (and the file plug-in ''does''
differentiate: you can grep the log for `FG_ERR_SOCKSCON` for those
errors). Also, the new browser plug-in
[https://github.com/shadow/shadow/issues/68 has these problems as well],
though we are not currently using that plug-in in our model.
I hope you can find the problem in Tor, especially since 3 of our separate
plug-ins are seeing this issue. I suggest search for the first occurrence
of `FG_ERR_SOCKSCON` and working backwards from there.
