High memory usage by the processes executed on remote server - RamMap

Question

High memory usage by the processes executed on remote server - RamMap

MaciekK 11

Hello,
I have a serverA where i have noticed high usage of the RAM memory. I have used RamMap and noticed that files that are used by another machine from Server B are taking over 10GB of memory. This memory usage grow over time. So in the few days it will be over 80GB!

Those files are on the USB drive attached directly to serverA.
From ServerB there is a AZCopy task that is uploading those files from serverA ( \serverA\sharedfolderA\ to Azure .

The question is why in the first place the processes executed on server B are utilizing memory on serverA?
Memory usage grow over time. This is normall situation? Is there a way to stop it or limit is somehow?

Any help much appreciated,

Your setup is not based on the recommended practice.
Why did you setup this way?
Try stop the task (just for test) and see if the problem persist?

I cannot directly attach disc to this Server B.

The memory usage now is very high, its about 100GB.

Have you any idea how to control this usage or limit it?

I have tried to empty standby list but it did't help.

This is related to some memory leak or?

On serverA run compmgmt.msc, and under System Tools, Shared Folders, Open Files. look to see if serverB has an open handle to any files.

The memory usage now is very high, its about 100GB.

How much physical memory does serverA have? In Task Manager, Performance, Memory, how much available memory does the system have?

There are already few files right now. The same files i can see at RamMap.
We are uploading from serverB big files (few TBs in multiple files). Server has 400GB of memory.
So those processes* took almost all free RAM on the physical server.

It all depends on the other applications that run on that server and their memory requirements. Any file that gets read will sit in the system file cache for some period of time. If no other apps need memory, then you might see those files for a longer time.

The counter that I've always watched was "Memory pages out/sec". That indicates that modified pages in physical memory need to be written to the page file, because other apps need more memory. That indicates that you do not have sufficient physical memory on the server.

To monitor my servers I configured logman to log key perfmon counters to a file every 15 minutes. Then when someone complained about server performance I would run them through PAL and let it do an analysis.

Hi,

You can open your task manager to check your committed memory.
You can see the Use Counts. If the top use count is “Metafile,” and if a large part of available memory is being used, you are experiencing the System File Cache issue that is described in the "Symptoms" section. You can verify this by using Performance Monitor to monitor the Memory\System Cache Resident Bytes counter and see the cache grow continuously over time.
You can try to update your OS to see if it works.

Best Regards,
Ansley
