Question

我有一个运行官方docker映像“ neo4j：4.0-enterprise”的Neo4J Enterprise Server 4.0。服务器已启动并运行了一个多月，其中包含3个已配置的数据库。服务器的执行方式为：

docker run --rm \
   -v /home/neo4j:/data -v /var/log/neo4j:/logs \
   -e NEO4J_ACCEPT_LICENSE_AGREEMENT=yes \
   -e NEO4J_dbms_mode=SINGLE \
   -e NEO4J_AUTH=neo4j/secure-password \
   -e NEO4J_dbms_memory_heap_initial__size=5100m \
   -e NEO4J_dbms_memory_heap_max__size=5100m \
   -e NEO4J_dbms_memory_pagecache_size=6900m \
   -p 7474:7474 -p 7687:7687 \
   --name neo4j \
   neo4j:4.0-enterprise

在neo4j浏览器控制台中执行一个非常简单的CYPHER失败，其中一个数据库（沙盒）出现以下错误消息：

MATCH (n:IdentityProviderType) SET n.protocol = n.value

Newly created token should be unique.

该数据库仅包含2个带有标签IdentityProviderType的节点。

在服务器重新启动docker restart neo4j之后，数据库无法联机，并在执行:sysinfo之后显示以下消息：

An error occurred! Unable to start database with name 'sandbox'

停止Neo4J服务器并执行：

docker run --rm -it \
   -v /home/neo4j:/data \
   -e NEO4J_ACCEPT_LICENSE_AGREEMENT=yes \
   neo4j:4.0-enterprise \
   neo4j-admin check-consistency --database=sandbox

如何从无法启动的数据库中恢复？

我在文档中找不到任何可帮助我解决此类问题的东西。

感谢您的帮助，
