有没有碰到过StackOverflowError的问题，数据量很小

[CorvusYe]

#32 有提过 看样子不是偶发的问题，方便提供一下报错日志吗，我看看哪里递归太深了

[Szt-1]

报错日志可能看不出来

很奇怪的错，发生在执行Dao里自定义方法的时候，springboot的测试用例可以通过，但是打包成服务对外暴露接口后，调接口就不行。报的这个错

[CorvusYe]

你先用 设置 -Xss2m 的方式看看能不能解决

看上去像是 antlr4 在解析 nGQL 的模板语法树上出的问题 自定义的 nGQL 很复杂吗

[CorvusYe]

参数设置成 -Xss108k 问题重现了 估计就是因为测试用例运行的 jvm Xss 的值比服务运行时的 Xss 大

如果是这样的话，为了避免服务运行不可预知的问题，建议把测试时的 jvm 参数也设置一下。

这个问题这边再做一下跟进

[Szt-1]

fetch prop on res_object @for(p in idList){ @if(pLP.last){ "${p}" @} @else{ "${p}", @} @} yield id(vertex) as id | get subgraph with prop 150 steps from $-.id yield vertices as nodes,edges as relationships | yield reduce(nodelist=list[],x in collect($-.nodes) | nodelist + x) as nodes,reduce(nodelist=list[],x in collect($-.relationships) | nodelist + x) as relationships

[Szt-1]

是这个for循环的问题吗

[CorvusYe]

看着还好，不复杂，for这个用法我也经常用😂，先提高一下Xss吧，如果能解决问题的话

[btbox]

我在循环边的时候，同时去查找 边的左右节点的时候，会导致内存溢出

[CorvusYe]

数据量大概在什么量级，最后是修改JVM参数吗

[Szt-1]

改了Xss的值为2m问题解决了

[yiyi3681]

我也遇到了这个问题，在for循环的时候使用任意一个dao的方法都会报StackOverflowError。但是如果用debug启动，则不会报错。

我用VisualVM分别监控了run和debug启动的线程状态，发现run只比debug多了一个线程：Monitor Ctrl-Break，查了一下发现这个是idea在run模式特有的线程，出现stackoverflow很可能跟它有关。 所以如果是用idea遇到这个问题，可以试下debug启动，我修改Xss后用run启动也没用（也可能是我修改的方式不对？）

-Xss2m 加在jvm那一栏也还是报错吗

不报错了，之前看来是没改对地方
