Good day.

I recently upgraded my IBM Intellistation M-Pro 6889-56U to the maximum amount of memory, 1024MB across 4-256MB DIMMS. O/S is NT4 with service pack 6a applied. Ever since adding this memory, the rundll32.exe file has been weird. When I first open Internet Explorer (5.5 with SP2 applied), rundll32.exe starts eating memory like there's no tomorrow - slams the swap file for about all it's worth and keeps "chewing." This goes on for several minutes, finally it will release and go back to some 2600k (according to the task manager). It will continue this way fine for some time until something else - often a pop-up window will launch a new instance of IE, will start the swap-file thrashing all over again.

Any ideas or patches/patched versions that will fix this? Sounds like a memory leak bigtime.

Thanks in advance,

Patrick

Another interesting article concerning rundll32 and IE 5.5:

http://www.cknow.com/cknewsletter/0407.htm

It says (among other things):

"Windows assigns "RUNDLL32.EXE SHSCRAP.DLL, OPENSCRAP_RUNDLL %1" to the .SHS extension by default and, when opened, Windows will unpack the scrap file and open or execute whatever is in the file. You will have no control over this once you attempt to open the scrap file."

Good luck,

Maxwell

This probably isn't what your problem is, but you should know its an option... I recently had this type of problem on a network infected w/ sircam worm...although all scans say the system is clean there has been alterations to the rundll32.exe file. I took windows 2000 disk and used expand (extract) command in the dos window replacing old copy with new and system was back to normal
