poll([{fd=8, events=POLLIN|POLLPRI|POLLERR|POLLHUP}], 1, 0) = 0 (Timeout) 這個timeout是導(dǎo)致的問題嗎，如果是要怎么知道是什么問提，如果是fd=8 的 sendto(8, "*2\r\n$6\r\nEXISTS\r\n$19\r\ndbdata_co"..., 42, MSG_DONTWAIT, NULL, 0) = 42這個嗎，但是這個是存到redis的統(tǒng)計數(shù)據(jù)量，會是redis查詢慢導(dǎo)致的嗎，但是查詢redis又正常。。，運行第二天這個start的網(wǎng)站打開就都504了，每次都要重啟，應(yīng)該如何找到導(dǎo)致的問題

walkor 打賞

Timeout沒問題。
sendto(8, "*2\r\n$6\r\nEXISTS\r\n$19\r\ndbdata_co 對應(yīng)的就是 fd=8 127.0.0.1:6379 redis操作。

從strace上看是業(yè)務(wù)有死循環(huán)或者大的循環(huán)一直在讀寫 127.0.0.1:27017 和 127.0.0.1:6379，進程在處理這個循環(huán)的時候無法處理其它事情就進入busy狀態(tài)了

  • 晚安。 2024-03-08

    老大 這些信息看起來像亂碼。是根據(jù)什么來看出來他是在做什么操作的嗎
  • z 2024-03-08

    因為他是大佬，一看就明白：）
z 
public static function countItemsByDb($dbname): array
    {
        $key=$dbname.'_countItems';
        $count=0;
        if (Redis::exists($key)) {
            $count=Redis::get($key);
        }else{
            $manager = self::createManager($dbname);
            $command = new Command(["count" => self::COLLECTION_PRODUCT]);
            $result = $manager->executeCommand($dbname, $command);
            if($result) {
                $count = current($result->toArray())->n;
                Redis::set($key, $count);
            }
        }
        $result=[];
        $result['total']=$count;

        return $result;
    }

這樣統(tǒng)計一次然后就直接取redis了，不應(yīng)該會導(dǎo)致busy，Redis::exists會判斷失敗導(dǎo)致多次統(tǒng)計嗎

  • walkor 2024-03-08

    27017 是什么端口？
  • z 2024-03-08

    mongo的
  • walkor 2024-03-08

    找下哪里有同時操作mongo和redis的
  • z 2024-03-08

    只有這一處，其他是redis和文件的, 改成文件保存了，，這個查找失敗次數(shù)是不是就會導(dǎo)致沒讀到

結(jié)帖，經(jīng)過幾天觀察，是predis導(dǎo)致的，去掉 ，用默認(rèn)的redis就正常
