我正在使用此WCF-WPF应用程序。我经常在异步XamDataGrid上收到此错误。尝试进行WCF调用并填充网格。我最初认为这与从WCF返回的大量数据有关,我通过仅为一个类别调用,使得调用返回数据非常小。这个错误随机出现,并不总是在同一组数据上。在15-20次尝试中足够可复制。WPF WCF MVVM OutOfMemoryException
我正在运行Windows XP(32位),双核,内存为4GB。当发生这种异常时,客户端机器仅使用大约2GB的RAM,而在服务器上W3WP仅使用800MB(6GB,3个内核,服务器上的总内存使用量为〜2GB)。
这只发生在XP机器上。在Windows 7上不会出现此错误。
请指导我如何解决此问题。
在此先感谢

如果你看电脑属性,它实际上报告4GB?在使用2GB内存时,您的流程需要多少钱? – 2010-10-12 17:22:30
是的..这是使用的总内存。该过程仅使用〜400MB – Bhuvan 2010-10-12 18:57:25
您是否检查过应用程序是否存在内存泄漏? – decyclone 2010-12-14 06:50:56
