氣流 sqlite3.operationalerror 數據庫被鎖定，然后調度程序崩潰

Question

我在 linux 服務器上運行氣流，它可以正常運行幾個小時，而不是氣流計划失敗。

這是日志的輸出：

OperationalError: (sqlite3.OperationalError) database is locked [SQL: u'SELECT connection.conn_id AS connection_conn_id \nFROM connection GROUP BY connection.conn_id'] (Background on this error at: http://sqlalche.me/e/e3q8)

我怎樣才能阻止這種情況發生？

Answer 1

當您在 SQLite 仍在處理另一個請求時向它發出請求時，可能會發生該錯誤。 它發生在我身上，我只是等了一會兒才提出另一個請求。
