Mule SFTP端點無法打開本地文件

Question

我有一個Mule流，它通過ftp服務器上的通用入站端點讀取文件，對數據進行一些修改，然后通過通用出站端點將文件寫入sftp服務器。 昨天它處理了60個文件。 在57處沒有錯誤，但在三個處出現了以下痕跡。 歡迎任何建議。

Answer 1

看起來是3個原因之一：

1. 您要寫入的文件夾的權限。
2. 文件路徑（或名稱）上的空格。
3. 文件路徑中的斜杠錯誤。

根據評論進行編輯 。

您可以嘗試配置maxThreadsActive來限制一次活動線程的數量。

<dispatcher-threading-profile maxThreadsActive="5" maxThreadsIdle="5"/>
