SYMPTOMS

On a computer that is running Windows Server 2008 or Windows Vista, you may receive the following Stop error message:
0x00000019 (00000021, parameter2, parameter3, parameter4)
BAD_POOL_HEADER
This behavior occurs when you change the Internet SCSI (iSCSI) configurations on the computer and retrieve some iSCSI connection statistics by using Windows Management Instrumentation(WMI).

Note
  • The parameters in this error message vary, depending on the configuration of the computer.
  • Not all "0x00000019" Stop errors are caused by this problem.

CAUSE

The iSCSI driver (Msiscsi.sys) does not manage allocated pool space correctly. This behavior leads to pool corruption. Therefore, when the corrupted pool is accessed, the system triggers the stop code 0x00000019.
