J4N*_*J4N 1 .net c# memory-leaks memory-management out-of-memory
我们在这里有一个问题,我们可以有一些问题OutOfMemoryException.
我们将检查如何减少内存使用量,但我的问题是为什么我在这一点上得到它.
根据Memory Profiler和Windows任务管理器,应用程序的权重仅为 400MB.
对于我所理解的(在此确认),对于32位应用程序,限制应该在2GB左右.我的电脑有16GB的内存,并且有足够的内存(超过4GB).
那我为什么现在得到这个错误呢？
我的问题不是为什么我的应用程序的内存增长,而是更多地了解为什么它现在已经发生了.我觉得这个限制不是固定的,但我找不到任何参考.
调用堆栈如果有帮助:
System.OutOfMemoryException: Out of memory.

编辑 我得到了完全不同的堆栈跟踪相同的异常:
