我有一个具有以下结构的csv文件：
h1_h2,hashtag1,hashtag2,coccurrence
39108234088393,9230981401776738405,11889764071793228909,2
48887306406636,2844752706633868157,14936885980370043276,2
...
文件中有1028112行。
我试图通过arangoimp
arangoimp --file E:\current_crawler\Data\edges\edges_for_graph_ep_83.csv --collection edges_temp4 --create-collection true
--create-collection-type edge --type csv --translate "hashtag1=_from" --translate "hashtag2=_to" --from-collection-prefix hashtags
--to-collection-prefix hashtags --translate "h1_h2=_key" --server.database "newDB" --server.username username --server.password password
并收到错误：

什么错误是什么？该文件没有问题，其中没有空行和重复的_keys。此外，当我重新引导系统并再次尝试时，没有出现此类错误，它已成功导入。
