+**Applies to:** :heavy_check_mark: Windows VMs
+
+This article helps you resolve an issue where a Microsoft Azure virtual machine (VM) experiences the **BAD_POOL_HEADER** bug check with the stop code 0x00000019.
+

+
+## Cause
+
+The pool is already corrupted at the time of the current request.
+
+This may or may not be due to the caller.
+
+A dump analysis is required to identify from where or what is causing the pool corruption.
+
+## Collect a memory dump for troubleshooting
+
+If you experience this error, [collect an OS memory dump file](./collect-os-memory-dump-file.md) and then [create a support request](https://ms.portal.azure.com/#blade/Microsoft_Azure_Support/HelpAndSupportBlade/overview?DMC=troubleshoot) for Azure support to troubleshoot and diagnose the issue.
