+# The UMDH tool generates warnings
+
+This article describes a known issue with the [User-Mode Dump Heap (UMDH)](/windows-hardware/drivers/debugger/umdh) tool that is installed with the [Debugging Tools for Windows](/windows-hardware/drivers/debugger/debugger-download-tools). The issue affects the UMDH tool included in the Windows SDK for Windows 11, the Windows Driver Kit for Windows 11, and the standalone toolsets.
+
+## Symptoms
+
+When the [UMDH](/windows-hardware/drivers/debugger/umdh) tool (also known as **umdh.exe**) executes, it displays the following messages and fails to capture memory allocations:
+
+```output
+Warning:
+Warning: UMDH didn't find any allocations that have stacks collected.
+Warning: Traces could not be collected because the Stack Trace Database is full.
+Warning: Increase the size of the Stack Trace Database using GFLAGS.
+Warning:
+```
+
+## Cause
+
+This is a bug in the UMDH tool included in the Windows SDK for Windows 11 and the Windows Driver Kit for Windows 11.
+
