             Summary: [OOM]Got an oom error when using iotdb(CQ?)
                 Key: IOTDB-2423
                 URL: https://issues.apache.org/jira/browse/IOTDB-2423
             Project: Apache IoTDB
          Issue Type: Bug
            Reporter: FengQingxin
         Attachments: image-2022-01-18-10-17-30-097.png, image-2022-01-18-10-21-51-829.png, image-2022-01-18-10-22-03-399.png, iotdb.log

使用16核32G内存运行默认配置下启动的IoTDB，在本机使用bm模拟实时写入（无压力）2个存储组管理30个设备，每个设备30个传感器。

启动后设置多个CQ任务（具体数量可参考mlog内容）。一段时间（2天？）后IoTDB报错OOM如下图：

该环境磁盘空间充足{*}!image-2022-01-18-10-22-03-399.png!{*}

附录压缩文件内包含相关使用的iotdb和bm（均含问题日志）。

iotdb.log是jstack -F <pid> 导出的信息
