问题现象：
所有涉及查询nebula的接口都会报类似的错误
对应的内存使用如下：
在04:00的时间，做了pod重启，nebula才恢复可用
涉及的查询：
MATCH (v:ad_scene_tag) WHERE NOT ()-[:IS_PARENT_OF]->(v) RETURN v;
MATCH (p:ad_scene_tag)-[:IS_PARENT_OF]->(c:ad_scene_tag) WHERE id(p) IN $parentIds RETURN id(p) as parentId, c as child;
MATCH (p:ad_scene_tag)-[:IS_PARENT_OF]->(c:ad_scene_tag) WHERE id(p) IN $parentIds RETURN id(p) as parentId, c as child;
