Thread: Storage error: [File chunk write error: Cannot allocate memory.] error

Hi,

I'm new user with rtorrent and rutorrent.

I just bought my Kimsufi 2G. After that, I installed rutorrent thanks to the topic http://forums.rutorrent.org/index.php?topic=608.0 . It works well when I had some torrents. However, when I had more than 20 torrents for seeding and about 4 downloading torrents. It occurs the error "Storage error: [File chunk write error: Cannot allocate memory.]".

I found some articles on the Internet which said I must edit my rtorrent.rc. But I don't know where is the file. I couldn't find the file on /home/<rutorrent_user> and /var/rutorrent/rutorrent/conf/users/<rutorrent_user>. I'm using multi-user rutorrent.

What is the best setting for my server to fix the problem? My server is Kimsufi 2G, Celeron 1,2Ghz, 2G RAM, 1TB HDD.



Many thanks,

the .rtorrent.rc file is in the user home directory, it has the '.' at the beginning which makes it a hidden file. Just log in using shell, and type cd and it will take you to your home directory, then type ls -a and you should see it in the listing.

I use the same server and below are the settings I use, which seem to work fine from me, adjust the directory settings according to how your system is organised.

Code:

# BitTorrent
max_downloads_global = 0
max_uploads_global = 0
min_peers = 30 
max_peers = 150 
min_peers_seed = -1 
max_peers_seed = -1


max_uploads = 150


download_rate = 0
upload_rate = 0


# Directories
directory = /home/'username'/rtorrent/downloads


session = /home/'username'/rtorrent/.session


schedule = watch_directory,5,5,load_start=/home/'username'/rtorrent/torrents/*.torrent






# Network
port_range = 50000-52999 
network.scgi.open_port = localhost:5000
network.http.ssl_verify_peer.set=0
port_random = yes
use_udp_trackers = yes 
encryption = allow_incoming,enable_retry,prefer_plaintext
network.max_open_files.set = 1024 
network.max_open_sockets.set = 1536 
network.http.max_open.set = 48 
network.send_buffer.size.set = 4M 
network.receive_buffer.size.set = 4M
dht = disable
peer_exchange = no




# Hash
check_hash = no
hash_read_ahead = 30
hash_interval = 5
hash_max_tries = 5
pieces.preload.type.set = 1
max_memory_usage = 3500M

4 torrents downloading is A lot, because the more torrents you have active the more your HDD drive has to work and it it's too much it will temporarely write in the RAM. This error occurs when RAM is full.

The only possible way to solve this, if possible, is to set the memory configuration higher, if it's too low.
Can you please post your rtorrent configuration?

Hi Arakasi, Many thanks. I see many differences between your .rtorrent.rc and my .rtorrent.rc file. Especially:

scgi_port = 127.0.0.1:23876
port_range = 23877-23877

Should I change scgi_port and port_range like your settings?

After changing the file, should I restart my server or do something else to apply new settings?

Hi Magister, this is my setting file.

scgi_port = 127.0.0.1:23876
encoding_list = UTF-8
system.umask.set = 022
port_range = 23877-23877
port_random = no
check_hash = no
directory = /home/<user>/downloads
session = /home/<user>/rtorrent/session
encryption = allow_incoming, try_outgoing, enable_retry
schedule = watch_directory,1,1,"load_start=/home/<user>/rtorrent/watch/*.torrent"
#schedule = untied_directory,5,5,"stop_untied=/home/<user>/rtorrent/watch/*.torrent"
trackers.enable = 1
#min_peers = 40
#max_peers = 100
#min_peers_seed = 10
#max_peers_seed = 50
#max_uploads = 15
#download_rate = 0
#upload_rate = 0
use_udp_trackers = yes
dht = auto
dht_port = 6881
peer_exchange = yes
#hash_read_ahead = 10
#hash_interval = 100
#hash_max_tries = 10
execute = {sh,-c,/usr/bin/php /var/rutorrent/rutorrent/php/initplugins.php <user> &}

The port range is not relevant for this error, but you can change it if you want to.
Your server tries to write on the HDD and when the HDD can't keep up with the speeds it temporarely writes in the memory.
Go to rutorrent/rtorrent settings/connection/other limitations / memory
It is possible that you have set this too low, in which case you should change the file that Arakasi has mentioned and change max memory to something like 3277MB. (Works for me)
After that you can either reboot your server or you can restart rtorrent.


EDIT: In your rtorrent.rc file there should somewhere be

max_memory_usage = ????MB

???? = some number
In my file I have it set to 3277MB.
Please check in rutorrent/rtorrent settings/ connection / other limitation / memory
If it's already set to something like 3500MB or more you can nothing to prevent this error and you have just too many torrents downloading at the same time and your server can't keep up, otherwise change it and restart rtorrent or your whole server.

After changine the port, I see the following error. How to fix it? And how to restart rtorrent only? I always reboot my server to apply new setting. Many thanks,

[26.10.2011 21:29:31] No connection to rTorrent. Check if it is really running. Check $scgi_port and $scgi_host settings in config.php and scgi_port in rTorrent configuration file.

Ok first question: Is there any particular reason why you changed the port? You do know that this won't solve your error.
This error means that rtorrent is not running.
Type

/etc/init.d/autodl

(In my case I have renamed this whole things - in your case it's probably something like rtorrent or so)
just type

/etc/init.d/
ls

And check if you have rtorrent there, then do /etc/init.d/rtorrent ...

Leave the ports as it was previously, as these port details are reflected in ruTorrent, so you would need to go and change the config there. Better just to leave it as it was installed. Also your directory settings should all be fine as they are.

If you are using private trackers turn dht and peer exchange off

dht = disable
peer_exchange = no

Many thanks. I change back the port and restart rtorrent. It works well.

Command to call rtorrent is:

/etc/init.d/autodl_<rtorrent_user>
