Bug#595527: siege: [error] descriptor table full sock.c:108: Too many open files

[Nicholas Doyle]

Not a siege error; caused by your client OS' limit on maximum number of
open files.
This is adjusted with 'ulimit' command.
e.g. ulimit -n 10000
To check, ulimit -a
and you should then see
open files                      (-n) 10000
