[GitHub] [iotdb] xufwind95 opened a new issue #5215: 数据库执行一段时间后，有大量假死的查询出现
xufwind95 opened a new issue #5215:
URL: https://github.com/apache/iotdb/issues/5215
**问题描述**
- iotdb在线上运行一段时候后，出现很多长时间不终止的查询
- 不做任何处理再次执行和这些查询相关的语句(使用相同的timeseries)，新查询也会失去响应
- 查询其它的未出现在这里面的timeseries，也会出现这种情况
- 查询数据库，能找到很多这种处于假死状态的查询语句
**配置**
- 系统 CentOS Linux release 7.6.1810
- iotdb版本: 0.12.4 单节点
**业务数据流程**
- 使用etl工具streamsets，从kafka抽取数据，通过mqtt协议写入到iotdb
- 下游为多个客户端执行分析查询，存在多个客户端查询同一个timeseries的情况
- 上游从kafka到iotdb的流程，从监控看一直是正常的

刚重启了，看不到之前的stack日志，重启完，在页面狂点了几下，又出现这种情况了，下面是部分stack日志，不够的话我找QQ群把stack日志文件传过来：

日志通过QQ群发了哈，查询出现假死的是啥情况啊，是我们什么地方没操作对么，升级版本能不能避免呢

方便用jstack -l pid > jstack.log把iotdb目前的堆栈打出来，放到这里不，我们看一下。
另外，可以把处于假死的查询sql复制一下，粘贴在issue里。
> 不做任何处理再次执行和这些查询相关的语句(使用相同的timeseries)，新查询也会失去响应
> 查询其它的未出现在这里面的timeseries，也会出现这种情况
这两句的意思是说，目前iotdb无法响应如何查询吗

这些未关闭的结果集会导致内存泄漏，最后导致什么查询都不出结果。

- KILL QUERY <QUERY_ID> 后，这些假死的查询仍然存在；
- 日志中能看到: WARN o.a.i.d.q.c.QueryTimeManager:71 - Query is time out (2000ms) with queryId 45057 ,但是连接始终无法释放
- 重启后假死查询全部消失

@jixuan1989
我觉得这个问题应该就是没正常关结果集或者 statement 导致的啊...reopen 的疑问在哪?

找到了，处理数据过程中出了问题，最后没执行到关闭那一步，我处理下程序，感谢

I did not find any log files on QQ group.
Is the log too large? why not upload the files here directly?

这次出错执行的sql是这个: select time, XXX_point_name from root.abc.def order by time desc limit 10 offset 1947370;
这个报错后，当前执行跟这个timeseires有关的其它查询还能执行，像 select time, XXX_point_name from root.abc.def order by time desc limit 10;
长时间过后这种语句应该也不能执行了……
