以下是一些信息：
应用程序在RDS上运行，有15-25个用户使用该应用程序
可用内存：32 GB
平均已使用内存：17 GB
永远不会出现这种情况，即已用内存达到30 GB（最高峰值约为23 GB）
CPU很好，平均40％，使用的峰值为60％
每个应用程序实例的RAM使用量随每个实例的使用量增加到约1.5 GB。
根据VS Profiler和其他探查器（包括JetBrains之一），对应用程序进行了多次剖析，内存泄漏为0，
[App使用Telerik库
[App使用实体框架
我有点困惑，不知道在哪里寻找潜在问题。优化花费了我数周的时间，而且进展顺利-我设法解决了典型的内存泄漏和内存分配问题，有时应用程序需要手动启动GC.Collect（），但这种情况很少发生。当OutOfMemoryException命中时，也没有任何模式，使我不知道在哪里寻找问题。因此，我正在寻找经验丰富的WPF开发人员，以便与我分享有关此类问题的经验。
最后一件事情：
我认为应用程序对于WPF来说太大了，这是由于经典WPF内存的增长（在几个小时的时间内应用程序的内存使用量从60K上升到1.5k），但是除了解决这个问题，我别无选择。
有什么想法吗？
很难找出这样的确切原因，但我可以建议一些故障排除机制。
您的堆栈跟踪建议您使用的是telerik gridview。尝试将其注释掉或替换为普通的gridview，看看是否仍然有异常。这样，至少您可以确定哪个元素是罪魁祸首。确认引起问题的元素后，请尝试通过继承同一类型来创建自定义控件。然后在所有方法中添加日志，调用基本方法。这样，您将不会同时失去功能，可以确认问题所在。
检查您是否遇到某种无限循环。调用堆栈建议，当尝试渲染所有元素时，它的内存不足。如果所涉及的某种ItemSource太大而使用循环依赖控件，则可能会发生这种情况。
