hello,
I have a shared 10Gbps Seedbox without root rights and i have the problem when I seeding the leechers peers lost the connection.
At the beginning the upload runs very fast and then he breaks completely or goes down and then goes up again.
There is no entry in the deluge.log.
Is the cache value adapted to your free memory on the server? Do not forget the x16
Have you installed the plugin Itconfig and selected the performance preset?
The present should have changed the cache settings, so if this is your free memory afterwards this is fine (no swapping/memory issue).
The only remaining is your Deluge/libtorrent version but if you have compiled or installed last version from PPA repo it should be fine
