ubuntu系統(tǒng)
Warning: file_put_contents(/xxxx/log//17-03-22.txt): failed to open stream: Too many open files in /xxx/common/function.php on line 323

這是方法是寫日志，用的是file_put_contents方法，按理說寫完日志就關掉了文件連接了，而我的work就看了3個進程，就導致了這個問題，請問如何解決？

調(diào)試發(fā)現(xiàn)是curl_init造成的，但是有關閉，系統(tǒng)卻一直保持連接

protected function _wget($url, $post_data = null)
    {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
        curl_setopt($ch, CURLOPT_TIMEOUT, 15);
        if ($post_data) {
            curl_setopt($ch, CURLOPT_POST, 1);
            curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
        }
        $response = curl_exec($ch);
        if ($response === false) {
            system_log('獲取遠程數(shù)據(jù)失?。? . curl_error($ch));
            curl_close($ch);
            return false;
        }
        $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
        curl_close($ch);
        if ($http_code == 200) {
            $ret = json_decode($response, true);
            if ($ret) {
                return $ret;
            }
            system_log('獲取遠程數(shù)據(jù)返回異常內(nèi)容:' . $response);
        } else {
            system_log('獲取遠程數(shù)據(jù)返回異常狀態(tài)碼:' . $http_code . ',返回內(nèi)容為:' . $response);
            return false;
        }
    }
