[Dovecot] Error: imap-login: Can't connect to auth server at default: Resource temporarily unavailable

[Matt Roman]

It appears the problem is in this function:

int net_connect_unix(const char *path)
{
        struct sockaddr_un sa;
        int fd, ret;

        memset(&sa, 0, sizeof(sa));
        sa.sun_family = AF_UNIX;
        if (strocpy(sa.sun_path, path, sizeof(sa.sun_path)) < 0) {
                /* too long path */
                errno = EINVAL;
                return -1;
        }

        /* create the socket */
        fd = socket(PF_UNIX, SOCK_STREAM, 0);
        if (fd == -1) {
                i_error("socket(%s) failed: %m", path);
                return -1;
        }

        net_set_nonblock(fd, TRUE);

        /* connect */
        ret = connect(fd, (void *)&sa, sizeof(sa));
        if (ret < 0 && errno != EINPROGRESS) {
                close_keep_errno(fd);
                return -1;
        }

        return fd;
}


This function is returning -1 and the server is crashing - Most likely because of a socket error.

The error message from the socket is "Resource temporarily unavailable"

If anybody knows why that would happen, I might be able figure out a solution.

Thanks!
