服务器用的是阿里云的,1核1G
-
neo4j(社区版3.5.3)部署在上面后,page cache是128M, max-heap是512M,剩下分给系统
-
启动后neo4j在服务器上内存占到82%左右,始终稳定
-
在本地打开neo4j desktop后连接都正常,本地电脑:i7 8700k, 16G内存
-
库里有3万个节点,7万个关系, 在desktop上做一些查询后,desktop会越来越卡,但内存和cpu占用无增加,无过载,cpu一直就5%左右,内存40%左右
-
desktop越来越卡,在执行过某个查询后,服务器的neo4j进程会突然关闭,不知是什么原因

16号和17号都有出现neo4j在服务器上闪退的现象,但是日志没有任何关于闪退的记录,3.16号那个stopped是我手动关闭的。

在浏览器chrome上也会出现越用越卡的现象
如果是服务器配置的问题的话,neo4j占用内存一直稳定在82%左右,cpu也没有过载的现象,因为都是远程连接服务器上的neo4j,为什么本地的浏览器和desktop在经过多次查询后会越来越卡?如果在本地上跑本地的库,从来都没有这些问题,都很好很快。 实在是不知道这是什么问题?还请各位老师,大牛帮帮忙想想办法,看看是咋回事啊。十分感谢!
