Could it be that similarly to kqueue on *BSD the Linux kernel unregisters/removes the handle automatically when it gets closed? And that dovecot closes it before unregistering it from epoll?
I don't know enough about epoll to answer that. I do see that in src/lib/ioloop-epoll.c, the "io_loop_handler_init()" function calls this, which sounds related.:
fd_close_on_exec(ctx->epfd, TRUE);But again, I am not very familiar with the specifics of epoll. Maybe somebody else on this list knows? This means the fd will be closed on exec() but I mean the case where the fd is closed by hand without exec().
And to answer my own question (question/answer 6): http://www.die.net/doc/linux/man/man4/epoll.4.html
I think it might be the cause of the error message.
Thanks, Bill
