Emmanuel Lecharny commented on DIRMINA-683:
-------------------------------------------
Postponed. I have no idea how to check if it's still a pb, and if it's MINA
related :/

> The error code -70015 corresponds to APR_NOTFOUND. I've also tracked it down
> into the APR code, and it looks like the problem comes from the kevent
> syscall returning ENOENT when MINA is doing the Poll.remove() call.
> I should note that the same code functions "normally" on Linux using the APR
> Transport, so I'm not sure if the problem is MINA's use of APR or APR's use
> of kqueue/kevent on FreeBSD.
