Going to fire a scheduled task to run every 30 minutes or so on a few of them.

They all start with this: The server was unable to allocate from the system nonpaged pool because the pool was empty. Full on hangs, so I can’t get in to see what ate the memory. Not seeing anything in real time looking like too many handles. Any ideas here gang?

From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Kennedy, Jim Sent: Monday, September 11, 2017 12:20 PM To: '[email protected]' Subject: [NTSysADM] 2008 R2 Hyper V guests OoM Just started a couple of weeks ago. I suspect an August update so I may cross post this later over on Patch Management. 2012 R2 Hyper V host (2 of them) with a mixture of 2008 R2 and 2012 R2 guests. Only the 2008 R2’s are exhibiting this behavior, they are all low usage machines. They are all set to dynamic memory and have been running for years without issue. One is only an FTP server that accepts 4 connections a night for an automated data transfer. And the incoming connections are IP restricted on our ASA, so it isn’t like it is getting flooded with hacking attempts. These boxes are varied in their use FTP, internal only web server, RDP Gateway, generic file server…… They crash shortly after a 2019 from srv. “The server was unable to allocate from the system nonpaged pool because the pool was empty.” Setting them to a fixed memory on the slightly larger than what I would expect them to need seems to have fixed it. Any other ideas?
