SYMPTOMS
The message transfer agent (MTA) may leak memory from allocations that are made in emsmta!CCryptContext::HrInit. If you obtain a UMDH dump file, it shows a consecutive increase in memory usage with stacks that are similar to:
ntdll!RtlDebugAllocateHeap+000000FD
ntdll!RtlAllocateHeapSlowly+0000005A
ntdll!RtlAllocateHeap+000008C2
KERNEL32!LocalAlloc+00000074
rsabase!MakeNewKey+00000014
rsabase!CPInflateKey+000001CB
ADVAPI32!CryptGetUserKey+00000068
emsmta!CCryptContext::HrInit+000000C3
ntdll!RtlDebugAllocateHeap+000000FD
ntdll!RtlAllocateHeapSlowly+0000005A
ntdll!RtlAllocateHeap+000008C2
KERNEL32!LocalAlloc+00000074
ADVAPI32!BuildVKey+0000000A
emsmta!CCryptContext::HrInit+000000C3
ntdll!RtlDebugAllocateHeap+000000FD
ntdll!RtlAllocateHeapSlowly+0000005A
ntdll!RtlAllocateHeap+000008C2
KERNEL32!LocalAlloc+00000074

ADVAPI32!CryptGetUserKey+00000068

CAUSE
This problem may occur if a handle is allocated, but is never released. This causes the leak.
