uploadify 上傳問題

以前使用uploadify上傳檔案都沒有錯誤，最近做一個程式，使用uploadify上傳log記錄檔，大部分都能上傳成功，包括formData的參數都能成功，但是有極個別的log檔案上傳的時候上傳不成功。
在伺服器端列印 $_POST 和 $_FILES，都為空白。
記錄檔名稱都是統一格式的，日誌也都是 utf-8編碼，但是有些可以成功，有些不能成功，有哪位大神碰到過，請指點一下，謝謝！

以下是uploadify的debug資訊

在伺服器端列印 $_POST 和 $_FILES，都為空白
是空白，還是空數組？
如果是空數組，則表示上傳沒有實際進行進行
如果是空白，則表示上傳的檔案大小超過了 post_max_size 的限定

還需要分別檢查各個轉寄機的max_post_size 踩過這個坑

果然是超大小了，只設定的上傳檔案大小，沒設定POST大小，
