Re: [Dovecot] RE: epoll error when running as proxy

...

imap-login: io_loop_handle_add: epoll_ctl(op=3, fd=10, ret=-1, errno=2): No such file or directory

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?

Thanks, Bill
