Since I decided to get a new motherboard to try to solve what I thought was a memory problem, I also decided (on a whim) to look into the rtorrent rc file.

Came across this site. Turns out the reason the xen server kept hanging may have been related to the max memory usage option… I’ve made some changes… we’ll see how they work.

I need to re-visit that site since there’s so much info on there, that I’d like to read and absorb.

The current .rtorrent.rc file that I’m using is this:

# This is an example resource file for rTorrent. Copy to:
 # ~/.rtorrent.rc and enable/modify the options as needed. Remember to
 # uncomment the options you wish to enable.

# Maximum and minimum number of peers to connect to per torrent.
 min_peers = 40
 max_peers = 100

# Same as above but for seeding completed torrents (-1 = same as downloading)
 #min_peers_seed = 10
 #max_peers_seed = 50

# Maximum number of simultanious uploads and downloads per torrent.
 max_uploads = 5

# Maximum number of simultanious uploads and downloads.
 max_uploads_global = 30
 max_downloads_global = 60

# Global upload and download rate in KiB. "0" for unlimited.
 download_rate = 0
 upload_rate = 30

# Default directory to save the downloaded torrents.

directory= /mnt/tower/downloads/.started/

#Log file
 #execute_log = /var/log/rtorrent.log

# Default session directory. Make sure you don't run multiple instance
 # of rtorrent using the same session directory. Perhaps using a
 # relative path?
 session = ~/.session

# Watch a directory for new torrents, and stop those that have been
 # deleted.
 schedule = watch_directory,5,5,load_start=/mnt/tower/downloads/.torrents/*.torrent
 schedule = untied_directory,5,5,stop_untied=

# Close torrents when diskspace is low.
 schedule = low_diskspace,5,60,close_low_diskspace=100M

# Stop torrents when reaching upload ratio in percent,
 # when also reaching total upload in bytes, or when
 # reaching final upload ratio in percent.
 # example: stop at ratio 2.0 with at least 200 MB uploaded, or else ratio 20.0
 schedule = ratio,60,60,"stop_on_ratio=500,500M,2000"

# The ip address reported to the tracker.
 ip = aonsen.homeip.net
 #ip = rakshasa.no

# The ip address the listening socket and outgoing connections is
 # bound to.
 bind = 192.168.0.113
 #bind = rakshasa.no

# Port range to use for listening.
 port_range = 55100-55200

# Start opening ports at a random position within the port range.
 port_random = no

# Check hash for finished torrents. Might be usefull until the bug is
 # fixed that causes lack of diskspace not to be properly reported.
 check_hash = yes

# Set whetever the client should try to connect to UDP trackers.
 use_udp_trackers = yes

# Alternative calls to bind and ip that should handle dynamic ip's.
 #schedule = ip_tick,0,1800,ip=rakshasa
 #schedule = bind_tick,0,1800,bind=rakshasa

# Encryption options, set to none (default) or any combination of the following:
 # allow_incoming, try_outgoing, require, require_RC4, enable_retry, prefer_plaintext
 #
 # The example value allows incoming encrypted connections, starts unencrypted
 # outgoing connections but retries with encryption if they fail, preferring
 # plaintext to RC4 encryption after the encrypted handshake
 #
 encryption = allow_incoming,enable_retry,prefer_plaintext

#
 # Do not modify the following parameters unless you know what you're doing.
 #

# Hash read-ahead controls how many MB to request the kernel to read
 # ahead. If the value is too low the disk may not be fully utilized,
 # while if too high the kernel might not be able to keep the read
 # pages in memory thus end up trashing.
 #hash_read_ahead = 10

# Interval between attempts to check the hash, in milliseconds.
 #hash_interval = 100

# Number of attempts to check the hash while using the mincore status,
 # before forcing. Overworked systems might need lower values to get a
 # decent hash checking rate.
 #hash_max_tries = 10

# Max number of files to keep open simultaniously.
 #max_open_files = 128

# Number of sockets to simultaneously keep open.
 #max_open_sockets = <no default>

# Example of scheduling commands: Switch between two ip's every 5
 # seconds.
 #schedule = "ip_tick1,5,10,ip=torretta"
 #schedule = "ip_tick2,10,10,ip=lampedusa"

# Remove a scheduled event.
 #schedule_remove = "ip_tick1"

# max mem usage
 max_memory_usage = 536870912

# When the torrent finishes, it executes "mv -n <base_path> ./share/torrents/"
 # and then sets the destination directory to "./share/torrents/finished". (0.7.7+)

on_finished = move_complete,"execute=mv,-u,$d.get_base_path=,/mnt/tower/downloads/"
