存算分离的CN节点 内存泄露风险

[kkkkwe5]

为了更快的定位您的问题，请提供以下信息，谢谢
【详述】存算分离的CN节点 有一台机器 内存很高 过几天 内存就打满 然后会报内存不足
【背景】就跑着一些视图任务 可能查询数据比较大 但是内存充足的时候是没问题的
【业务影响】 视图任务无法执行
【是否存算分离】 是
【StarRocks版本】例如：3.1.13
【集群规模】例如：3fe（1 follower+2observer）+3be
【机器信息】fe 8C32G CN 16C64G

主要是 be节点内存高 但是子进程 内存都不高 机器重启后 过段时间又会慢慢打满 每次都是一台机器内存较高

[LIANGCHAOHUA]

有内存24小时的监控图吗？

[kkkkwe5]

[kkkkwe5]

服务器自从重启完 内存就一路在上涨

[trueeyu]

@kkkkwe5

存高 但是子进程 内存都不

可能是AwsSDK内存泄漏导致的，升级到3.2吧

[trueeyu]

[Enhancement] Upgrade staros v3.2.1

[kkkkwe5]

升级到 3.2.10 跑了几个大查询 内存 又上去下不来了 剩下的内存又不知道干啥去了

[trueeyu]

随便跑几个大查询，内存就下不来了？

[kkkkwe5]

下面是当前内存情况 帮忙看下

就一个小时前 写了几个查询 同时 导入了一些数据 内存就下不来了

[trueeyu]

这个HeapProfile拿的时间太短了，最好是内存上升前开始，然后内存高峰的时候结束，再获取下这个

[kkkkwe5]

行 那这两天观察着 上升了 之后 我再获取一次

[trueeyu]

可以加我下，有问题随时沟通。

[kkkkwe5]

怎么加啊 我看只能私信啊

[kkkkwe5]

今天做了控制变量发现是 SELECT table A使用UDTF进行数据打散并INSERT table B中，导致使用的内存持续占用不释放 重复执行多次后 内存打满

曲线图如下

打满后的内存文件如下 可以与昨天的对比一下

le A使用UDT

那估计UDTF实现的有问题，导致的内存泄漏，可以将BE使用的jdk换成jdk8，并且配置下Jvm内存上限试试

[kkkkwe5]

我们是存算分离啊 用的 jdk11 能确定是哪的问题吗 换成jdk8就可以？

[suguangqiang]

是的,下不来了.

[trueeyu]

当前CN/BE对于JDK11还没适配好，而且默认应该没设置JVM使用的内存上限，JVM自身应该默认是机器内存的1/4吧。

[kkkkwe5]

使用udf时看 jvm内存情况 看来java分配的对象 都可以回收啊

会不会是C++调用的时候 处理 有内存泄露呢？
