搜索弹性引擎不断杀死代码我如何解决它？

如何解决搜索弹性引擎不断杀死代码我如何解决它？

我使用运行 gunicorn 实例的烧瓶服务器设置了弹性搜索。我的问题是弹性搜索每隔几个小时就会崩溃，我必须重新启动它。

服务状态如下所示：

● elasticsearch.service - Elasticsearch
   Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; disabled; vendor preset: enabled)

这是烧瓶错误日志的样子：

我能做些什么来修复它？以前它偶尔会崩溃，但现在每隔几个小时就会崩溃一次。可能的问题是什么？如果我需要添加更多详细信息，请告诉我。
