紅寶石進程吃100％cpu

當即時通訊嘗試從我的應用程序（使用devise）登出應用程序掛起和紅寶石吃了100％的CPU，重新啓動服務器後，它stil frezeed（無法加載頁面）。它只有當我下降並重新創建我的數據庫。我使用PostgreSQL，試圖切換到MySQL，沒有幫助。使用雜種（與webrick一起發生）。紅寶石1.9.2，軌3.0.9紅寶石進程吃100％cpu

林真的不知道會發生什麼呢？

UPD *這是凍結不僅發生在註銷，這是發生隨機:(也可以在Mac其他開發商還沒有這個問題，即時運行Ubuntu 11.10，試穿了10.04，仍然有它。

100％cpu聽起來像某種無限循環，並且有無數的可能的罪魁禍首是什麼可能導致這種情況。在'after_save'鉤子中保存模型是一個，無限重定向是另一個。是其中之一，但它也可能是其他東西完全（甚至不一定是一個無限循環，對於這件事）。 – Frost

我檢查兩次，沒有無限循環掛鉤 –

你可以嗎？用戶模型的模型代碼如何？你給我們的東西還不足以讓我們甚至開始查明錯誤來自哪裏。 –

嘗試打開cache_classes在發展中.rb
