Php7.0-fpm高負載CPU

我有一個錯誤。他隨機出現。工作可以2-3天是正常的，但經過一些事件開始高負荷CPU screen Php7.0-fpm高負載CPU

我做的php-fpm的strace的，當它出現

更新的內核不解決這個問題呢？僅幫助幫助重新啓動php-fpm進程您能指導我嗎？由於

是'apt-get的upgrade'是巧合還是什麼，你可以在這些隨機事件看？ – YvesLeBorg

@YvesLeBorg我做apt-get升級沒意義，看不到巧合 –

那是因爲你的插座它試圖做一個寫時，他不能：

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

既然你沒有改變的源代碼的任何手段，你需要降級PHP版本和看看它是否能夠在沒有此套接字問題的情況下完成任務。
