Exception: [AbstractOptionHandler.cc:73] errorCode=28 We encountered a problem while processing the option '--seed-ratio'.
-> [OptionHandlerImpl.cc:254] errorCode=1 seed-ratio must be greater than or equal to 0.0.
Usage:
--seed-ratio=RATIO Specify share ratio. Seed completed torrents
until share ratio reaches RATIO.
You are strongly encouraged to specify equals or more than 1.0 here. Specify 0.0 if you intend to
do seeding regardless of share ratio.
If --seed-time option is specified along with
this option, seeding ends when at least one of
the conditions is satisfied.

Possible Values: 0.0-*
Default: 1.0
