any experience with rtorrent?

hey i was wondering if anyone here has a lot of experience with rtorrent and could answer a quick question of mine.

i have rtorrent setup on my vps to download torrents with but the problem is that if i let it get above a certain download rate it seems that this causes it to crash--and no error is given.

could this be a problem with rtorrent or is it more likely a problem with my limited amount of memory on the vps (256mb)

any feedback is appreciated, thanks!

even you use linux with the lightweight torrent client like rtorrent, in my opinion having the ram only 256mb isn't enough at all, maybe if you use it on a slow connection it'll work, but on 100/100 even it's shared by a number, still doesn't enough, try to increase your ram

ok that's what i figured, ill just keep it tuned down for now i guess, i'll buy more ram next month.

just curious, on what hosting is your vps ? thanks

have you tried turning your buffer up? I know doing so will use more memory but 256megs should be fine to run rtorrent on. seems kind of awkward it is carshing. my guess is the hard drive is locking up, but i'm not expert with rtorrent. i kind of ditched it for azureus (i know I'm lame lol)

please explain what you mean "turning your buffer up"

like the bigger the buffer the more memory is used and the less hdd is used. at high speeds a hard drive will choke unless the mem is buffered a god amount.

First I will show you my VPS specifications:
VM: Xen
OS: CentOS 5
Mem: 256ram / 512 swap
Client: rTorrent 0.7.9 + libTorrent 0.11.9 (custom build)
Other Things I'm running, sshd, httpd - apache, ftpd - vsftp, bnc - psybnc
identd - oidentd. I think I covered everything... (I'm NOT running any kind of VNCs)

I'm running rTorrent successfully without any glitches (well,
sometimes when the transfer rates are very high, I get errors
related to Disk Buffer, and the chunks are dropped). I can
download more then 5 torrents simultaneously with out any
problems, and I can download big torrents (the biggest
torrent I've downloaded was 11gb)

The client itself never crashed on me. I'm running it inside
'screen' so if I got disconnected, the client will be still alive
inside the screen. (and I recover it with screen -r).

please supply more information, like conf (.rtorrent.conf) logs
and specs.

ok well how do i turn my buffer up?

supply

Code:

---

cat /proc/sys/fs/file-max

---

and

Code:

---

ulimit -n

---

(Make sure you're running this with the same user whose
running the rTorrent application)

:angry: Read my previous post, and supply the specs and .rtorrent.rc.

[jonathon@filonome ~]$ ulimit -n

if the box only has 256 megs and you set rtorrent to use 256 megs there will not be enough memory for the OS or anything else you are running. Try setting it to 200megs.

That's what virtual memory is for..

yes aka using the hdd, hitting an overload and crashing

So you're telling rtorrent uses almost all of physical memory to do the job ?

i'm saying he has it setup to use more then there is physical memory available and that is what is causing it to crash.

i have it set at 250, what should i put it down to?

200 like he said you dumb fuck

I AM A FEMALE dumb fuck

:lol:

Where are the mods to sort the kids out? :|
