Re: NT? Physical Memory Dumps? You don't say.
A couple of questions.
Do you have a fair number of applications that your company has developed internaly, or tweaked to meet their specific needs? Does your SW/Eng staff develop their own DLL's via some sort of DLL Maint app for users to `update' to the new set of DLL's?
The number one way to get NT to do a memdump is to address iomem that is reserved for the kernel or is being occupied by the kernel. The reason I ask the above questions is that our topology is also a mess, VMS, Solaris, AIX, Linux, NT 4.0, NT 3.5, Win2000, MAC, OS/2 , our SW/Eng that develop corp apps ( desktop ) stuff write or heavily tweak a lot of apps, even MS Office200. NT/200 systems seem to be memdumping pretty regularly (once every 120 days per desktop?).
Just a guess, but I would guess that your company is running something that the kernel *really* doesn't like. At my company the NT SW/Eng development team tried to resolve this by coding custom DLL's, which seemed to reolve the issue, until they made another change to the tweaked software that is.
So glad I am a *nix developer. :D
Solution = fire all NT programmers && install Linux on all machines.
Just kidding.
