A Windows Server 2003-based computer becomes unresponsive because of a memory manager trimming operation that is caused by an indeterminate module that requests lots of memory
A Windows Server 2003-based computer becomes unresponsive. This unresponsive time may last from several seconds to two minutes. During this time, all applications and services on the computer stop working.
When you monitor the working set size of a process, you may find that the working set size of the process decreases. This information indicates that the memory manager is trimming all processes on the computer to satisfy a large memory allocation request. Typically, the trimming operation is triggered by the following functions:
•
MMAllocateContiguousMemory
•
MmAllocateContiguousMemorySpecifyCache
Unfortunately, you cannot determine the driver or the module that triggers the memory allocation request operation to request the large amount of memory.
