SYMPTOMS
Consider the following scenario:
- You have a program that allocates a large block of contiguous memory in Microsoft Windows Server 2003. For example, this program allocates a 1.5-gigabyte (GB) block of memory when the program starts or after it starts.
- This program loads the Hnetcfg.dll library.
In this scenario, the program may intermittently not start. Or, after the program starts, you may experience intermittent program failures. If you troubleshoot these program failures, you may determine that they occur because the program could not successfully allocate the large block of contiguous memory.
CAUSE
This problem occurs because the Hnetcfg.dll library has an image base address of 5F270000. If the Hnetcfg.dll library is loaded at this address, you may experience memory fragmentation of the Windows user address space. You experience this fragmentation because the Hnetcfg.dll library is loaded at approximately 1.6 GB into the address space.
