The server was unable to allocate from the system nonpaged pool because the
pool was empty .

We keep seeing the above errors and our server crashes. I am trying to
understand the basics here as to what is the nonpaged pool ?

And how does the pool become empty and what does it want to allocate ?

Whats a paged pool if theres a nonpaged pool ?

Thanks

Kernel mode components can choose between paged- and nonpaged pool
memory pool, depends on there needs. User mode applications use always
the paged pool, except they lock memory to keep them resident. Paged
memory can be paged out, this means that your hard drive will be used as
memory. Nonpaged pool memory can't be paged out.

AFAIK if more nonpaged memory is required than available.

Hi

Nonpaged pool. The portion of shared system memory that cannot be paged to
the disk paging file. Nonpaged pool memory can be accessed at any time
without causing a page fault.

Page fault. A page fault occurs when a thread accesses a page that is not
in memory. For more information about paging and other memory management
topics, see "Evaluating Memory and Cache Usage" in the Server Operations
Guide of the Microsoft® Windows 2000 Server Resource
