Question

我正在尝试使用脚本将批量数据插入Neo4j。一段时间后，脚本会出现以下异常。

PHP Fatal error:  Uncaught exception 'Everyman\Neo4j\Exception' with message 'Unable to execute query [400]:
Headers: Array

    [Content-Length] =>  3031
    [Content-Type] =>  application/json; charset=UTF-8

同样的查询在控制台上工作，并从发生异常的同一点重新启动脚本一段时间再次工作，直到它再次失败。捕获异常并使脚本休眠几秒钟不会破坏脚本。

有关此处可能发生的事情的任何建议吗？

更新：添加了示例查询

START a = node:?("?:?"), b = node:?("?:?")
            MATCH a-[c1:ACTIVITY_LIST*]->z, z-[r1:ACTIVITY_LIST]->y
            WHERE z.TIMESTAMP >= '.$time.' AND y.TIMESTAMP < '.$time.'
            CREATE n = {?}, clist = {COMMENT_ID: ''}, a-[:IN_?]->n, n-[:OUT_?]->b, n-[:COMMENT_LIST]->clist, z-[:ACTIVITY_LIST]->n, n-[:ACTIVITY_LIST]->y
            DELETE r1
            RETURN n;

插入数据时出现Neo4j异常
