Thread: Rtorrent crashes when the speeds are high?

I have a little problem i cant solove.

I have a VPS, with a gigabit connection and that is good :)

And i am running rtorrent with rutorrent and autodl-irssi support. Folowed this guide.



Everything is working fine, but when i start large torrents 4 gb ++, the seedbox starts to build up greate speeds. And its going on to around 30-40 MB/s, then rtorrent crashes. And i have seen some run these servers on 80++ MB/s.

This is the error i get when it crashes:
rtorrent: std::bad_allocate

I also get a SCGI_LOCAL error when i starts rtorrent:
(21:06:16) Using 'epoll' based polling.
(21:06:16) XMLRPC initialized with 519 functions.
(21:06:16) The SCGI socket is bound to a specific network device yet may still pose a security risk, consider using 'scgi_local'.

And in my rutorrent, it just stands it lost connection, maybe rtorrent is down?

Someone have a tip or answer?

It's crashing when you're well into a busy session.. so my money would be on low resources e.g. memory. You can try increasing how much shared memory is allocated, reducing upload slots or chuck chunk sizes and see if any of those net you a quick fix. Troubleshooting it properly would take considerably more time and effort.

Perhaps as a starting point, explore /proc/user_beancounters and see if anything stands out vis a vis low resources

For the SCGI_LOCAL error, how is the sgi-port configured in rtorrent.rc? Is it configured at all? e.g.,

Code:

scgi_local = /root/.rtorrent/rpc.socket
schedule = chmod,0,0,"execute=chmod,777,/root/.rtorrent/rpc.socket"

The purpose of this is to open a local rpc socket for rtorrent. The second line sets RW access for the socket file to avoid permission errors.

.

My server was so full of crap, so i decided to re-install all. And now everything works :D

and i get almost 100 MB/s <3
