# 系统报错"error = 113"以及告警"Grpc socket closed."

#### 问题现象

在调优过程中，可能会出现如下类似报错和告警，错误码113表示Grpc服务不可用，导致调优中断。

- 第一种报错

```
[WARNING] TUNE(176715,aoe):2024-06-05-15:34:17.806.812 [nca_client.cpp:188][NCA]202128 Service:

```


- 第二种报错

```

[ERROR] TUNE(176715,aoe):2024-06-05-15:34:17.877.052 [nca.cpp:447][NCA]202128 RunModel: [Session: 145]
Failed to execute RunModel
.
error = 113
```


#### 解决方案

出现错误码113以及告警"Grpc socket closed."，表明当前Grpc状态码为"UNAVAILABLE"（不可用），解决办法是：用户重新调优。
