A Memory Leak Occurs When Wininet.dll Is Repeatedly Loaded and Unloaded (814417)


The information in this article applies to:

  • Microsoft Windows CE .NET 4.0

SYMPTOMS

After you use a network-enabled program that frequently loads and unloads Wininet.dll, any of the following symptoms may occur:
  • You may receive "Out of memory" error messages.
  • The system may report that it is low on memory.
  • Programs may stop working unexpectedly.

CAUSE

If Wininet.dll is loaded and unloaded repeatedly by a process, several kernel objects (handles) are not freed. The accumulation of used handles may cause the system to become low on memory. The handles are freed when the process that loaded and unloaded Wininet.dll ends.

RESOLUTION
