fd_ebadf is called when you give libev an invalid file descriptor - this
is likely an applciation bug (fd_ebadf is very slow, but select and poll
do not report *which* file descriptor is wrong, so libev has to check
every single one).
you likely see it repeatedly because you ignore the EV_ERROR bit in your
watcher and just add the file descriptor again (ignoring that bit is fine
if your code is perfect :).
Both of these are application bugs - you have to make sure that the file
descriptors you give to libev are valid, open, poll'able file descriptors,
and you should check for EV_ERROR conditions and not start the watcher
again.
