Evt ID 7 The dynamic memory driver memory operation [Remove memory] failed with error: STATUS_SUCCES

Hi,

We have a Windows Server 2019 that is currently set on Dynamic Memory which randomly freezes and shows up a bunch of


Event ID 7

The dynamic memory driver memory operation [Remove memory] failed with error: STATUS_SUCCESS.


I searched on Google and didn't really find any article that explains and how to resolve it.


Thanks

Did you ever resolve this issue? We are also experiencing this issue. Believe it has got something to do with Office365 (since we can match the beginning of the issue on several VMs simultaneously with the installdate of Office365 update).

Yes but this is not something related to O365 instead more of a server freeze up when on Dynamic RAM

The server manufacturer will likely be your best resource to trouble shoot problems with the hardware.

Does this refer to a hardware issue?

Just from what you posted yes, it sure sounds like it.

Hmmm...weird coz besides this troubled VM on that host, we have a separate host which also hosts a terminal server just like the first vm also doing dynamic memory and it's experiencing same issue.

We're planning to set it to static and see if that would fix the issue without troubleshooting the host/hardware

Did this help? We got exact same problems and Evt ID.

Peter, did you get anywhere with this? We have a server doing exactly the same since the 9th July, wondering if it's an update that's caused it, as the timing seems to be too much of a coincidence with your case and ours.

HI, We're experiencing exactly the same issue, since the 9th July 2021, did the change from Dynamic to Static RAM allocation resolve your issue?

0 Votes 0 ·

Yes, it did help, after changing it from Dynamic to Static, the issue didn't persists.

Thanks, we will try it too, it’s been causing lots of issues, and has been hard to find a proper fix.

I still wonder why dynamic memory has just decided to stop working.

It would have helped to mention more details like it is a virtual machine. What hypervisor is being used? Is this error on host or guest? Might check the event logs on host and guest for further information.

apologies for the incomplete info. Yes this is a vm

Host 1 has RDP2
Host7 has RDP1

Both are terminal servers vm and both were configured as dynamic memory and both are Server 2019. Both are Hyper-V. Event log shows the title

even logs errors I believe are succeeding errors after some services stops but we found out an event log under Applications and Services logs > Microsoft > Windows > Hyper-V-Guest-Drivers

Event ID 7 The dynamic memory driver memory operation [Remove memory] failed with error: STATUS_SUCCESS

After rebooting the vm, then this event ID 7 stops.

error: STATUS_SUCCESS

Are you sure there's a problem? The log was not enabled by default on my hosts. I did enable it so I can monitor.

The log is not located on the host, the log came from the vm itself

For some reason the host has no error or critical logs, most of the logs are coming from the vm

error: STATUS_SUCCESS

Are you sure there's a problem? STATUS_SUCCESS seems like a good result. Is it an error or informational level? I see occasionally 101, 102 informational Microsoft-Hyper-V-Guest-Drivers-Admin.

Hi,
Please check if there’s any event ID, for example, in Hyper-V VMMS/Hyper-V Worker, if yes, please provide the detailed error information.
Best regards,
Mico Mi
