Release cache Window server

We have a dynamic AX AOS server that always need to reboot to server in case some program run slowly.

Is there a quick way to clean up window memory rather than rebooting the server to affect daily operation ?

It depends what is taking the memory or other resources

When its running slowly have a look at memory and process utilisation in "Task Manager" and it theres on that high you can use a

NET STOP "Service Name"
NET START "Service Name"

just restarting the AOS service releases the Dynamics AX cashe, how many AOS's do you have on this one server? and how much memory does the server have?
AXISHKAuthor Commented:
A AOS server running on Window 2008 (64bit RAM) 12GB RAM supporting around 64 users. Tks

Is there a command to simply release the memory cache on Window, rather than reset any service in AOS in order not to affect any scheduled task ? Tks

Sorry forgot to ask what version of ax?? And which CU do you have?
AXISHKAuthor Commented:
AX2009. What do u mean CU and where can I check it ? Tks
Damon ReptonOwner\DirectorCommented:
go to

and you need the number below

AXISHKAuthor Commented:
Kernel Version 5.0.1500.5616
Application version : 5.0.1001.96
Damon ReptonOwner\DirectorCommented:
ok so thats ax2009 SP1 Hotfix Rollup 7

what is your memory at on the server? 80% 90%?

is the server maxing out on memory?

why do you want to flush it??

Attached please find the resource at the current moment. Any comment ?
Damon ReptonOwner\DirectorCommented:
ok so not too bad really.

looks like you might have a few server side processes running via batch maybe, this is why the CPU is in heavy to light use, memory looks ok, does it get much higher than that??

i would schedule a weekly service restart maybe Saturday or Sunday night, is this a virtual server?
AXISHKAuthor Commented:
What CPU & memory value will indicate  a h/w performance ? Is 30% CPU usage is still high ? How about the memory ?

Tks again.
Damon ReptonOwner\DirectorCommented:
30% is fine, your screenshot shows a spike, but again nothing to worry about, if your server was running at 90% CPU constantly you might have an issue, but from the screenshot you don't.

same with memory, you don't want to go into paging, but from the screenshot you are not at risk of that.

you might want to look are DynamicsPref this helps monitor Dynamics AX performance also SCOM has a management pack for AX
