我的neo4j服务器正在自动停止和启动，

我正在运行我的

neo4j社区版3.5.5

版本，在

aws实例中使用8GB内存

最初几个月，它运行得很好，并在毫秒的时间内得到了结果，但现在几天它开始自动停止和启动。有时它在几个小时内根本没有启动，甚至我们也手动启动了它

谁能帮我一下吗。我得到下面的日志

这可能是因为您正在运行大量合并操作，并且没有创建正确的索引，或者没有尝试在配置文件中增加堆大小。
请正确设置您的帖子格式tanks@TheCrusher，我的内存设置是memory.heap.initial\u size=3500m memory.heap.max\u size=3500m memory.pagecache.size=2000m
