--- Comment #1 from Dave <da...@alfar.co.uk> ---
Although this bug was raised against 2.0 in 2006, this behavior still exists on
the latest 2.4. It can easily be reproduced by restarting Apache while running
a simple curl loop against a phpinfo script (in other words while the server is
only handling a single request to the CGI)

As ap_graceful_stop_signalled() was removed in 2.3, I suspect a modern
equivalent before the connect() in cleanup_script() would be:

    /* Don't connect while we're shutting down */
    if (ap_mpm_query(AP_MPMQ_MPM_STATE, &rc) == APR_SUCCESS &&
        rc == AP_MPMQ_STOPPING) {
        return APR_EGENERAL;
    }

although I cannot vouch for the appropriateness of the reported workaround.
