Errors: Broken Pipe and Connection closed by peer

I'm desperate. Getting these warns and just can't solve them, even by hoster can't. How?

Is it true? /* Now pass any remaining response body data to output filters */ if ((rv = ap_pass_brigade(r->output_filters, brigade_stdout)) != APR_SUCCESS) { if (!APR_STATUS_IS_ECONNABORTED(rv)) { ap_log_rerror(APLOG_MARK, APLOG_WARNING, rv, r, "mod_fcgid: ap_pass_brigade failed in " "handle_request_ipc function"); } return HTTP_INTERNAL_SERVER_ERROR; }
