At some point when I updated to 4.4.0 version of bittorrent, the tracker bttrack stopped working. In the logfile /var/log/bittorrent/bttrack.log, I was getting messages like that:

# Log Started: 2008-10-05 07:26 UTC
Traceback (most recent call last):

rsize = self.add_data(infohash, event, ip, paramslist)

I googled the problem; this is related message. The problem persists for more than a year in Fedora. (I am currently running Fedora 8, but I believe I had it since 7). As a workaround, edit the file /etc/sysconfig/bittorrent and add the option "--twisted 0" in tracker's options. For example, my corresponding line reads:

TRACKOPTS="--min_time_between_log_flushes 4.0 --show_names 1 --hupmonitor 1 --twisted 0"


tip: I usually run bttrack and btseed with low priorities. To do that, edit the file /etc/init.d/bttrack and modify the line

/sbin/runuser -s /bin/sh -c "$prog --port $TRACKPORT \

as

/sbin/runuser -s /bin/sh -c "nice -n 15 $prog --port $TRACKPORT \

You can adjust "15" to a priority of your liking from 0 to 15 (the higher number, the lower the priority). I do a similar modification in the file /etc/init.d/btseed.
