一、该问题的重现步骤是什么？

1. 不太好容易复现

2. resource服务可以正常使用2~3天，之后所有文件都会上传失败

3.系统不能上传文件后，jar包内存和cpu正常，不像内存泄露

二、你期待的结果是什么？实际看到的又是什么？


三、你正在使用的是什么产品，什么版本？在什么操作系统上？

bladex微服务版，3.0.1版本   linux服务器

四、请提供详细的错误堆栈信息，这很重要。


五、若有更多详细信息，请在下面提供。

    参考这个试试：https://sns.bladex.cn/article-14995.html

    作者追问:2023-04-27 18:31

    这个方法已经尝试过了，没有用。这个帖子是解决找不到临时文件。

    我这边的异常情况是Too many open files。核心代码我们都没有动过。

    回答: 2023-04-27 18:31

    请问用的是minio么？有可能minio的新版驱动，把流的自动关闭取消掉了，可能要自行关闭，你参考这个新的写法试试。

    下载bladex-tool，修改对应源码，然后执行mvn clean install把修改安装到本地，再跑跑看有没有问题。还有个临时的解决办法就是提高linux ulimit的值，先提高后让他报错时间延长，等问题解决再重新部署。

    @SneakyThrows
public BladeFile putFile(String bucketName, String fileName, InputStream stream, String contentType) {
   makeBucket(bucketName);
   String originalName = fileName;
   fileName = getFileName(fileName);
   try {
      client.putObject(
         PutObjectArgs.builder()
            .bucket(getBucketName(bucketName))
            .object(fileName)
            .stream(stream, stream.available(), -1)
            .contentType(contentType)
            .build()
      );
   } catch (Exception e) {
      e.printStackTrace();
   } finally {
      try {
         if (stream != null) {
            stream.close();
         }
      } catch (Exception e) {
         e.printStackTrace();
      }
   }
   BladeFile file = new BladeFile();
   file.setOriginalName(originalName);
   file.setName(fileName);
   file.setDomain(getOssHost(bucketName));
   file.setLink(fileLink(bucketName, fileName));
   return file;
}

    提高linux ulimit的值治标不治本，我先把代码改一下，看看情况再说

    作者追问:2023-04-27 18:31

    忘记讲了，是minio
