Hello Everyone,

Running on Windows 2000 Advanced server service pack 4

I am attempting to simulate SQL IO Patterns using SQLIOSim and receiving hundreds of VirtualProtect errors. See snippet below. From what I understand is this function is called during the transition of a page. Can this be a physical memory issue?

I have also attempted to add different physical paths same issue. Lastly, I ran the tool another server, same hardware, os, and patches, no issues.

<ENTRY TYPE='ERROR' TIME='15:07:34' DATE='02/15/09' TID='4744' User='Initial
Update' File='e:\yukon\sosbranch\sql\ntdbms\storeng\util\sqliosim\buffer.cpp'
Line='104' Func='ChangePageProtection' HRESULT='0x800701E7' SYSTEXT='Attempt
to access invalid address.'>

<EXTENDED_DESCRIPTION>VirtualProtect (0x055CA000, 4)
failed</EXTENDED_DESCRIPTION>

</ENTRY>
