Windows out of memory false positive

Question

After setting up two gpo's (one for applocker auditing, one for applocker event forwarding to a log server) some users get out of memory error message. F.ex. trying to open Firefox leads to the error message: not enough memory to run this application. Close some windows or programs and try again.

The task manager actually shows that there IS enough memory. After removing the affected computer from the policies, the error does not occur anymore. Tried to google and found desktop heap value issue. But it is already set to 1024, 20480. Somehow this error only occurs on 2 out of 4 computers. I don't know why.

Hi Ricardo,

Glad to know that you have identified the issue, however Please "Accept the answer" if the information helped you. This will help us and others in the community as well.

Thanks.

Answer 2

Just had the same exact scenario as you. Restarting resolved it for us.

Answer 3

Seems like the problem was caused by pushing the gpo's on a running system. After adding to the gpo the next day in the morning and a reboot the system runs very well and is not causing these errors. Maybe there were other gpo's or processes conflicting when forcing gpupdate manually.

Answer 4

Hi,

Just to check if all the PCs are updated with latest patches and updates? Any difference in the 2 PC that has the issue of Memory Leak, please check any Antivirus version DAT version and also any GPOs that could be linked ?

Disk Space, Memory Optimization, Page File settings etc.?

What is the resource monitor looks like, any event logs for the mem leak?

Can you try the same settings on a new build device? Verify all the settings, eliminate one by one each settings.
