當執行相同的遍歷查詢時，Arango會隨機重新啟動

Question

我正在運行從節點服務器到安裝了Arango的Ubuntu AWS實例的一系列同時請求。 Arangod是版本3.1.7

一切都運行良好幾周，但現在：

在隨機的基礎上，我在執行查詢時從節點獲得{Error：socket hang up}，總是相同的，並且arango似乎重新啟動，因為我得到{錯誤：連接ECONNREFUSED}所有其他查詢而。 它發生在6次中的1次，盡管我的數據在查詢之間沒有變化。

Web界面日志非常少，似乎無法解釋出現了什么問題。 Arangod似乎創建了一個日志文件，但很難解釋。 所有服務器指標都很好。

您對如何在這個問題上取得進展有什么想法？ 我的數據損壞了嗎？ 我該怎么知道？

這是我的日志文件的內容：

而且：

我相信引起麻煩的查詢是：

FILTER k.vertices[1]._id LIKE "Drop/%"
AND k.vertices[2]._id LIKE "Hint/%"
AND k.vertices[3]._id LIKE "Drop/%"
FILTER k.vertices[1].hostname != k.vertices[3].hostname
FILTER k.vertices[2].type == "article"
SORT k.vertices[2].createdAt DESC
LIMIT 0, 1
RETURN UNION (

Answer 1

經過大量的研究，我試圖簡單地升級到arangod 3.1.11。 問題似乎已經消失。
