关于在Azure App Service上托管的.NET 6 Web API中\ local \ temp上的自由空间的例外（即使那里有很多空间）

Question

我有一个.NET 6 Web API在Azure App Service（Windows，Standard Service Plan（S1：1））上运行

，有时我会得到此例外：

system.io.ioexception：磁盘上没有足够的空间。 ： 'd：\ local \ temp \ aspnetcore_7aca67c0-7d1f-40ba-bef3-9e58ea7444487.tmp'

这是最后一次发生的堆栈跟踪：

这是在各种API端点上发生的（IE各种控制器中的各种动作方法）。 奇怪的是，它正在发生在我没有执行任何文件编写活动的方法中。从表格从MySQL数据库查询的基本 SELECT * SELECT *是简单的GET请求，并返回结果。

现在，如果我转到Azure Portal，然后转到我的应用程序服务，然后到配额，我还有很多可用空间：

如果我去Kudu，然后是环境：

如果您看着最后两行，我在 d：\ home 和 d：\ local 上有足够的空间

吗？

Answer 1

看起来这里解释了。解决方案是启用对请求的缓冲。 ASP.NET Core将请求主体写入Windows Temp文件夹

M $ DOC以进行申请缓冲。

Answer 2

您的申请过程遇到了崩溃。这可能是由应用程序代码引起的。

建议监视崩溃的建议

Exception Code  
1 crash due to (0xE0434352 - CLR Exception)

如果以下检测器没有崩溃的例外详细信息，请建议客户通过遵循这些步骤启用崩溃监视。

1. 转到App Service Diagnostics
2. 选择诊断工具。
3. 单击崩溃监视从菜单选项中进行操作，然后按照说明进行操作。

HTTP服务器错误的建议

ExceptionType                              Method                         Count
System.IO.IOException   PropWorx.API.Services.Auth0Service+d__4.MoveNext    5
System.Threading.Tasks.TaskCanceledException    PropWorx.API.Middlewares.TenantIdentifier+d__4.MoveNext 3
System.IO.IOException   PropWorx.API.Services.Auth0Service+d__4.MoveNext    2

http 500.0错误通常指示应用程序代码问题。应用程序代码中的未处理异常或应用程序中的错误是通常导致此错误的原因。请检查代码。

---

我发现的问题，请在您的身边检查

1. nlog和mysql，请在您的应用程序异常中检查一下

     system.AggregateException：写入对记录器时发生错误。 （无法连接到任何指定的MySQL主机。）
    

2. 慢速请求执行

3. 您需要检查 appinsights 。您可以找到很多例外。

摘要

1. 请联系您的开发人员团队，让他们根据例外情况查看代码。

2. 启用本地cache

3. 请阅读本文，它也对您有用。

Answer 3

发布此问题后不久，我删除了Azure上的LogFiles文件夹中的所有日志（我是通过FTP / Filezilla进行的）。有很多日志文件可以返回很长时间。我不确定这些是否有助于我认为可能是对可用的临时存储空间的限制，但是已经过去了将近两个星期，而且我没有更多的“磁盘上没有足够的空间”。例外。

我将继续监视它。我不确定这是否是解决方案，但似乎有所帮助。尽管我不想无限期地将其保持开放，但我正在关闭这篇文章。

感谢大家的投入。
