The solution of inetinfo.exe at 100 % of cpu is to incress the virtual
memory at 150 % at less of the phisical ram memory.
Example
Ram memory 512
Partition of virtual memory c: free disc 2.0 GB
Virtual memory: 1.44 GB
Restart the computer and thats all.
I hope this help you.

note: you can use severals partitons to divide the virtual memory.
Sorry my english
No, I don't think this is a "solution" at all. InetInfo.exe has no magic
requirement that virtual memory be 1.5 times physical memory (IIS is not
aware of how much you've allocated as a pagefile/swapfile at all). Probably
rebooting the server fixed the "issue"
Next time inetinfo,exe is at 100% CPU for an extended period, use IISState
to find out what's going on inside:

Dear Ken:
This is a solution, and I assure you that I am solved the problem.
I use the IISState and is a good tool, I do not deny it, but that not
work with my problem.
I attempt to tell you that if the virtual memory is greater to the one
of the free disc space, I assure you that inteinfo.exe goes away to 100
% of the processor
I do not say that this is THE solution, I say that serves for many
cases. (Be surely)
Note: To increase the virtual memory to 150 % of the real memory is the
correct thing always.
Greetings

I'm sorry, but unless you can provide some technical reasoning for your
conclusion, I don't think this is one that's going to be recommended to
others.
IIS doesn't know how much virtual memory you have defined for pagefile.sys.
Why would CPU go to 100% if the pagefile.sys is lower?
I have seen many machines where pagefile.sys is lower and there hasn't been
100% CPU issue. If I write an ISAPI Filter with an endless loop, then I will
get 100% CPU, and changing the virtual memory setting will have *no effect*
whatsoever. So there is no 1-1 correlation between virtual memory setting
and 100% CPU issue.
Lastly, whilst 1.5 x physical memory might be a good general benchmark, it's
really up to the systems administrator to tune this as required. Otherwise,
please post some technical reference that shows that 1.5 is the magic
number. I don't think it exists.
Cheers
Ken

I'm afraid that there is no correlation to memory and CPU, as Ken says. You
are seeing a coincidental effect, not causational.
Take, as an example:
<%
for x = 1 to 1000000
y = x
Response.Write y 'send it to the response buffer
Response.Flush 'flush the buffer to keep memory overhead low
next
%>
This code will drive CPU to 100%, and most likely keep it there until the
script timeout (90sec by default) and use virtually no memory.
Further, all 32bit processes running on a 32bit build of Windows receives
the exact same amount of memory, 2GB; unless the /3GB flag is set in the
boot.ini. This memory is the same regardless of the pagefile or RAM
installed. The pagefile/RAM is only used to back the memory that may or may
not be allocated, but IIS has _no idea_ if the memory that it has allocated
is being backed by RAM or the pagefile. That is 100% owned by the Memory
Manager (MM for short).
For more info, I would recommend reviewing chapters 6 & 7 of Windows
Internals (MS-Press).
