Why is the nonpaged pool growing?

Question

Windows Server

There is a server on win server 2012 running hyper-v services, print service, and file services. It is used as a dump file and a print server. In the task manager, the nonpaged pool indicator, after a reboot, grows inexorably until it fills the entire RAM. After that the server wildly slows down. What can be wrong? installed kaspersky and it is disabled.

Answer 1

poolmon.exe shows which driver is leaking. Need to find and neutralize. The Internet explains in detail how to use it.

Answer 2

netio.exe - any thoughts on how to set up this global service so that it frees up memory?

Answer 3

Recommendations are standard: install all updates, update all drivers, remove unnecessary software.
In your case, almost certainly, these are connected "soft" printers a la hp 1xxx/2xxx series. Junior canons and brothers also sin. Yes, what is it. Almost all SOHO printers (not MFPs) sin with firewood cut under the enterprise. Hence the memory leaks. As soon as the memory is no longer enough, the use of swap begins and performance drops.
If there are such printers, then it is better to use a separate virtual machine for them, which can be regularly rebooted without damaging the process.
