spresenseの録音サンプルプログラム  
「Audio>application>recorder_wav」ファイルにて、  
10秒間録音をループさせ、連続して録音するプログラムに修正してみたのですが、  
15回ほど録音したところで、audio libraryの初期化が出来ずエラーが発生しました。  
エラーの原因・対策についてご教授いただければ幸いです。

【追記】  
また、エラーが発生しない場合でも、3時間ほどでプログラムがフリーズしてしまいます。その理由などについても心当たりがあればご教授いただけないでしょうか？

question
spresense
spresense連続録音での初期化エラーについて
最新版の v2.5.0で、

<https://developer.sony.com/develop/spresense/docs/release_arduino_ja.html#_v2_5_0_20220401>

で、下記のこのようにコードを変更して動作させたところ、特に問題なく連続動作していました。

`exitRecording` のラベル中の `exit` を `setup()` に置き換える。  
※`SDClass` には、`end()` がないので。

```

      puts("End Recording");
    
      ErrEnd = false;
      setup();
    //  exit(1);
    
```

ご参考まで。
