Php7.0-fpm高負荷CPU

Question

私にはバグがあります。彼はランダムに発生します。 5月2-3日の作業は正常であるが、それはこの問題を解決しませんか？

更新カーネルを生じたときに、いくつかのイベントが高負荷のCPUを起動 screen

後、私は、PHP-FPMにstraceの操作を行いますか ヘルプのみphp-fpmプロセスを再起動 私にアドバイスできますか？おかげ

Answer 1

あなたのソケットので、それは彼が傾く時に書き込みをしようとされている：あなたが変更ソースコードの任意の手段を持っていないので

write(8, "C", 1)      = -1 EAGAIN (Resource temporarily unavailable) 
rt_sigreturn()       = 56 

は、あなたのPHPのバージョンをダウングレードする必要があり、このソケット問題なしでタスクを完了できるかどうかを確認してください。
