Why am I getting " Errno 24 (Too many open files)" error?
Unless configured otherwise some clients will keep all the files in a torrent open during the downloading process. This error occurs with some of the larger multi-file torrents, which can have hundreds or thousands of component files. When the number exceeds the OS limit, the OS refuses to allow them all to be opened, preventing the client from accessing them. To resolve the problem either limit the number of files the client will have open at any one time or increase the OS limit for the number of open files.
