Downloads stop for no apparent reason #53

Open alganza opened 4 years ago

alganza commented 4 years ago

When I start the server (3.1.6) everything seems to work fine, both downloads and uploads start working within seconds. But after a few minutes, downloads stop for no apparent reason, while uploads keep going just fine. Immediately after I kill and start the server again, downloads start working again for a while, and then they stop again, until I kill the server and run it again.

It happens both, with the package from my distribution (Devuan) and the binary compiled by myself (3.1.6-git).

Not enough information. E.g. which network is it about? Try to find any clues that correlate with downloads stopping, e.g. any errors/warnings in logs? Show the output of sysinfo mldonkey command. Increase logs verbosity with set verbosity verb or set verbosity all

alganza commented 4 years ago

It happens to the donkey network downloads, which is the only one I'm using, so I can't tell if it happens to other networks too or not.

I've set verbosity all and I'll pay closer attention to the logs to see if I find something relevant.

I may be wrong, but it seems you are running out of disk space. This could stop your downloads but not your uploads.

HinTak commented 4 years ago

Not really - it is a 200GB disk with 900MB free, so the available space is about 0.4% which is rounded down to 0. You can run mldonkey at about 50MB free.

I'd suspect it is the network adapting and learning to block p2p traffic (many ISPs do these days), or the fair use part of p2p protocols kicking in - there is a built-in ratio you have to upload x amount to download y amount.

The same problem keeps happening with 3.1.7.git and 5 GiB free, as well as in a different server with the same version and 285 GiB free.
