【问题描述】：

我有 asp.net 网络表单应用程序。我将程序部署到 IIS 服务器并且程序运行良好，但所有用户的 InProc 会话经常同时死亡。 我知道应用程序池通常是回收的。我安装了 DebugDiagx64 程序并添加了这个应用程序池的日志。结果是这样的

Some exception details were omitted due to the following reasons
        The maximum number of stacks (MAX_CLR_EXCEPTION_STACKS_PER_EXCEPTION_TYPE = 10) for this CLR exception type have been collected: 'NOT_FOUND'
        The maximum number of stacks (MAX_CLR_EXCEPTION_STACKS_PER_EXCEPTION_TYPE = 10) for this CLR exception type have been collected: 'System.Threading.ThreadAbortException'
        The maximum number of stacks (MAX_CLR_EXCEPTION_STACKS_PER_EXCEPTION_TYPE = 10) for this CLR exception type have been collected: 'System.Net.HttpWebRequest'
        The maximum number of stacks (MAX_CLR_EXCEPTION_STACKS_PER_EXCEPTION_TYPE = 10) for this CLR exception type have been collected: 'System.ServiceModel.FaultReason'
        The maximum number of stacks (MAX_CLR_EXCEPTION_STACKS_PER_EXCEPTION_TYPE = 10) for this CLR exception type have been collected: 'System.Threading.ExecutionContext'
        The maximum number of stacks (MAX_CLR_EXCEPTION_STACKS_PER_EXCEPTION_TYPE = 10) for this CLR exception type have been collected: 'System.NullReferenceException'
        The maximum number of total stacks (MAX_CLR_EXCEPTION_STACKS_TOTAL = 100) for all CLR exception types have been collected)
        The maximum number of stacks (MAX_CLR_EXCEPTION_STACKS_PER_EXCEPTION_TYPE = 10) for this CLR exception type have been collected: 'System.Security.Cryptography.CryptographicException'

如何解决这个问题？

【参考方案1】：

我发现了问题。我使用的是 UDT 类型，Odac 版本有时会抛出异常并且应用程序池被回收。我不使用udt类型，问题解决了。
