```

## 问题原因

租户队列已经用满，需要释放。

```shell
req_queue:total_size=8193 queue[0]=0 queue[1]=0 queue[2]=7958 queue[3]=0 queue[4]=235 queue[5]=0 , large queued:0, multi_level_queue:total_size=0 queue[0]=0 queue[1]=0 queue[2]=0 queue[3]=0 queue[4]=0 queue[5]=0 queue[6]=0 queue[7]=0 queue[8]=0 queue[9]=0

```

## 解决方法

1. 重启这台 OBServer。
 2. 将这个对应租户的资源进行扩容（具体到 CPU 和内存）。
