Limit Memory usage on Exchange Store

I am looking to limit the Exchange Store. Our Exchange server contains all roles and is being installed to replace a current Exchange 2003 server. Currently all mail now flows through the
Ex2k10 server and 5 users have been moved to the new server. The server was installed roughly 45 days ago. The server has 16GB ram installed and runs Server 2012. Store.exe is taking 8GB and other services are beginning to have issues
and I would like to limit the amount of memory it uses. Since there are currently 5 users on the system I was going to limit the store process to 6GB with a minimum of 4GB which would theoretically leave 2GB free according to current usage. The issue I have
is the settings in ADSIEdit as outlined in several articles (example:
http://eightwone.com/2011/04/06/limiting-exchange-2010-sp1-database-cache/#comment-9125) do not exist in my current config? We have Exchange 2010 SP3 installed and all of the latest patches at least to 45 days ago. If necessary I will increase
the RAM in the future but IMHO the store should not currently need 8GB for 5 users

Came across sites recently where the information store process on an SBS 2011 box tends to take most of the available memory. In normal circumstances Exchange 2010 is designed to use as much memory as possible for performance optimization. As long as Exchange
2010 is running on it’s own, there’s no problem with that. The issues can arise in SBS 2011 environment, where there is SQL 2008 R2 installed alongside Exchange 2010 and SQL has similar optimization built in. As a result the performance of the system could
degrade by time and requires restart of Exchange/SQL services or rebooting the whole system.
To avoid this problem, you can limit the amount of memory Exchange is using. Start by opening ADSIedit – either click Start -> ADSIedit.msc, or navigate to Start -> All Programs -> Administrative Tools -> ADSI Edit.
Right click the root of the tree view on the left and select Connect To. . . On the Connection Settings screen select the Select a well known Naming Context option and from the drop down list choose the Configuration option.
Once connected to the Configuration Naming Context, navigate to the following item:
Configuration -> Services -> Microsoft Exchange -> ”Organization Name” -> Administrative Groups > ”Administrative Group” -> Servers -> ”Server Name” -> InformationStore
Right click Information Store and scroll down to msExchESEParamCacheSizeMax attribute and set the value according to your requirements.
Please note that Exchange 2007 works with 8kB pages and Exchnage 2010 works with 32kB pages. So if you want to limit the size of memory used to 4GB, you will need the following calculations:
Exchange 2007: 4 GB = 4.194.304 KB / 8 KB => 524288
Exchange 2010: 4 GB = 4.194.304 KB / 32 KB => 131072
If you have confirmed you have the correct numbers, you can click OK to save the settings and restart Microsoft Exchange Information Store service for the changes to take effect.
UPDATE: As it turns out, setting the msExchESEParamCacheSizeMax size only doesn’t seem to be sufficient. The limit has been actually applied only when the msExchESEParamCacheSizeMin size was set as well. In our
example the values would be set as follows:
Exchange 2010:
Min – 1GB: msExchESEParamCacheSizeMin = 32768
Max – 4GB: msExchESEParamCacheSizeMax = 131072
Exchange 2007:
Min – 1GB: msExchESEParamCacheSizeMin = 131072
Max – 4GB: msExchESEParamCacheSizeMax = 524288

Limiting Memory Usage of Exchange 2010sp1 store.exe on a Windows 2012r2 Server?

Hello,
I am running Windows 2012r2 Server with Exchange 2010sp1, 1 forest and 6 mailboxes. So this is not a heavy load for Exchange 2010sp1 to handle. The problem is the Windows 2012r2 server is also used as a file storage server. The problem is the Exchange 2010sp1
is using most of the 16GB of ram available and slowing down the server. Is it possible to limit the Exchange 2010sp1 store.exe to use less memory and if so what are the steps in Windows 2012r2 to complete this task.
I have read that it can be done through ADSI Edit. But the steps they explain are not for Windows 2012r2 and do not match.
Thank You,
Stan

Hi Stan,
Did you change msExchESEparamCacheSizeMax and msExchESEparamCacheSizeMin both attribute of Information Store?
Start ADSIEDIT.msc Navigate to Configuration > Services > Microsoft Exchange > <Organization Name> > Administrative Groups > <Administrative Group> > Servers > <Server Name> > InformationStore
http://eightwone.com/2011/04/06/limiting-exchange-2010-sp1-database-cache/
That ADSIEdit path shouldn't be different on Windows 2012 R2 because it doesn't depend on operating system and it should be always same in Configuration partition of Active Directory.
Besides....
Exchange 2010 SP1 (and SP2) is not supported now so suggest you upgrade to SP3. http://blogs.technet.com/b/rmilne/archive/2013/01/04/end-of-exchange-2010-sp1-support.aspx

Solaris 10 - Restrict memory usage

Bonjour,
I use Solaris 10 Release 6/06 on SPARC system.
I need to restrict the memory usage for users.
Unfortunately, for the moment, we can't increase the amount of RAM.
So, in a first time, I decided to use projects and max-shm-memory. But, this is only for shared memory segment, not real memory usage.
rcapd use SWAP instead of RAM ... it not solve my issue.
How can limit memory usage of an user ? It's possible of Solaris 10 (without zones) ?
Thx.
Guillaume

does ulimit help you? this applies to the shell rather than a user...

Exchange 2010 Store.exe Memory Usage

I have read about msExchESParamCacheSizeMax and it seems to do nothing with my server.
I am running Server 2008 R2 x64. With Exchange 2010 x64 with 1 Mailbox Store and 10 Mailboxes. The store.exe process sucks up anywhere from 11-13GB of Ram on my 32GB server.
What is the true way to limit the store.exe process or the database?

Hi Miller,
I agree with Amit.
We usually receive questions that Exchange service (store.exe) is using most of the memory on a mailbox server.
If another process should need the more memory, the Exchange store.exe process will released it as required. This is by design.
More details to see following blog:
Exchange 2010 store.exe service takes high memory utilization.

Exchange 2013 issue with High memory Usage on Mailbox server post SP1 update.

So we have been chugging along fine since Feb 2 2014.
I performed a migration from 2010 from the UK to the US doing "incremental" mailbox moves. (get in contact with me if you want to know how. But we moved 400 Mailboxes averaging at 2gb a piece from the UK to the US, over the transcontinental link.
& then the weekend of the final, had everyone & everything done by the end of the cutover weekend)
Any woot.
So I applied the 2013 SP1 a few weeks back, & have intermitantly been alerted to the memory spiking over 95%. For me (and for any exchange admin) when i get those types of alerts i drop everything & run to the nearest PC to see what is going on.
Now the first & second time, it was an issue with logs filling up the drives, & my clean log script not running to remove any logs older than 30 days. But since then it has been legitimate 95%+ memory usage.
For the most part its been 95-97 max, with 1 or 2 times hitting 98. After some time, the memory does drop back down to 94.
this is ....umm "fine" however it is becoming a nuisance, since most of the time it corrects itself. What i dont want to happen is get into the groove of saying "ah bah! its nothing" & letting it go.
the server has 16gb of memory in it, it is the Mailbox server (CAS /Frontend is on a seperate server)
below is a screen shot, so i know the Storeworker grabs whatever it feels like grabbing, however it does NOT EVER release memory. I also see the NodeRunner.exe (2 of them) is always around 900 almost a MB
now if i could somehow get the first 2 Storeworkers to drop down to 900ish, then that should alleviate my memory issues.
what I am m looking for is some type of "magic bullet" to put my memory issues at ease..

thats the problem & seems to be a misconception.
Exchange NEVER releases the memory when other things need it. As the users state in your thread you linked. (i came across that early in my search for a resolution). An example is if another admin & myself log into the backend server at the same
time & begin clicking around opening things, etc..Memory will go to 100% which = No Buenos.
There are numerous post all over the internet from people who say it releases, but them 5 more comments to that 1 saying that it does not.
I know what the process's do, however it seems like the SP1 has increased memory usage, as typically the Store.exe would only grab about 900-1000.
in terms of the noderunner, once again i know its role, however we are now 2 months+ live on 2013 post migration, I do not think it is still indexing all those emails.

Exchange 2013 Memory usage very low

Hi,
we have 4 Servers, 2 Mailbox Servers and 2 Database SErvers with DAG deployed on Exchange 2013 CU5.
We have about 420 GB in one database.
The Server has 40 GB Memory assigned (Windows VM), but only using about 12 GB of Memory.
Depending on this guide, this makes sense:
http://blogs.technet.com/b/samdrey/archive/2014/02/03/exchange-2013-memory-ram-allocation-by-the-store-with-an-example.aspx
But, as this is only a database server with no other services on it, how can i increase the memory consumed by Exchange?

Are the Outlook clients in online mode?

S.o.s. how to set a memory usage limit in flash cs4?

flash is using 1 200 000 k. and i cant work in this situation. i know that i can limit the usage of memory in ps cs4. but i dont know how i do it in flash. is there a way of limiting the memory usage or making flash use memory as much as this?

Thats all my poblems!!!
I used File Monitors from Sysinternals and I see, that Flash operated with C:\xalan\xercesImpl.jar (on my system), and can't find C:\Program Files\Adobe\Adobe Flash CS4\META-INF\services\org.apache.xerces.xni.parser.XMLParserConfiguration and others...
I temporary remove xalan - well - thats all - CS4 successfully compile, test, check codes !!!
1) Adobe CS4 used Xerces Apache (and configurated himself, without us)
2) Use Sysinternals to detect other file-problems
On my machine Flash 8, CS3, CS4 - for adjusting project compatibility.

Some questions about the limit of memory usage of Adobe flash player in different OS & Web Browser

Hi Adobe experts,
I'm from HP, and now using Adobe flash player making some products about massive data displaying.
For my target, I need to show more than 200 K rows in client web browser, using AdvancedDataGrid.
And that may needs more than 200M to cache the data in Web browser memory space.
So, my questions are:
Does there any memory usage limit in flash player?
Say, if we have 4G bytes of physical memory in machine, in Windows, how much can I use in flash player?
Also, if we have 4G bytes of physical memory in Linux, how much can I use in flash player?
Does it depends on the Web Browser?
Say, is there any difference between different web browsers?
If the limit exists, can we control the limit?
Say, can we define some parameters in the tag in web page to expand the limitation?
Or, can we try to control this limitation by the Flash player management which exists in the Windows Control Panel?
Best Regards

1. Yes. The Toolkit for CreateJS is an extra downloadable extension for Flash CS6. It will publish html and js files that will provide the animation instead of the swf that you would normally publish. The success or failure of the resulting javascript version of your animation is the result of working within the constraints of the toolkit. You are pretty much constrained to using the timeline in Flash for your animations. If you work only in Actionscript, then the output will be very disappointing.
2. Edge outputs javascript, css, and html to give you an animation. The user interface allows you to design within the constraints of what Edge can do. You can preview and adjust and tweek your animation as you work. Edge is an html5 tool. It can create html5 animation. It is not a replacement for Flash. It is something that you can use instead of Flash to embed animation in html.
The problems and benefits of each are unique. Neither is a good substitute to learning javascript, css and html5. If you don't understand the code that is created from each of these tools, you can easily end up with huge, bloated, files that perform poorly. I'm very biased toward actually knowing what is going on. If I need to edit something, I want to be able to go into the code and make a change, not add an additional chunk of code to work around what was there. I don't use the timeline at all, and so nothing that I have will publish using CreateJS. Well, it will publish, but nothing happens because there is nothing on the timeline to translate.
You can download a trial of Flash CS6 and try the Toolkit for yourself. Edge is still in free preview, you can get a copy at http://labs.adobe.com and try it to see how it works.
Also, if you're not using the Greensock Animation Platform with Flash, have a look at that. It has recently been extended to provide Javascript analogues for most of the Libraries. http://www.greensock.com/

Having a problem with Excessive "modified" memory usage in Win7 x64, upwards of 3.6GB, any suggestions?

I have 6GB of ram, a fresh install of Windows 7 x64, and the screenshot shows what happens after leaving my PC on for a couple days. (3782+MB being used by modified memory ATM).
http://wow.deconstruct.me/images/ExcessiveMemory.jpg
Any ideas on this?
Edit:
Added this after first round of suggestions
http://wow.deconstruct.me/images/NotSoExcessiveMemory.jpg
This is uptime of around 2 hours.
The first image is of uptime of around 3-5 days.

Matthew,
The only reason why these pages are kept on the modified list indefinitely is because the system doesn't have any available pagefile space left. If you increase the size of the pagefile the system will write most of these pages to disk and then move them from the modified list to the standby list. Standby pages are considered part of "available memory", because they can be reused for some other purpose if necessary.
Whether this would "fix" the problem or not depends on what the actual problem is. If it's an unbound memory leak then increasing the size of the pagefile will simply allow the system to run longer before it eventually hits the maximum pagefile size limit, or runs out of disk space. On the other hand, if it's a case of some application allocating a lot of memory and not using it for a long time, then increasing the pagefile might be a perfectly valid solution.
Allowing the system to manage the size of the pagefile actually works well in most cases. Pagefile fragmentation (at the filesystem level) can only occur when the initially chosen size is not large enough and the system has to extend it at run time. For win7 we have telemetry data that shows that even for systems with 1 GB of RAM, less than 0.1% of all boot sessions end up having to extend the pagefile, and this number is even lower for larger amounts of RAM. If you think you are in that 0.1% and your pagefile might be getting fragmented, you can manually increase its minimum size such that the total system commit charge stays below 80% even if you run all your apps at once (80% is the threshold at which the pagefile is automatically extended). This will make sure the pagefile is created once and then stays at the same size forever, so it can't fragment. The maximum size can either be set to the same value as the minimum, or you can make it larger so that the system is more resilient to memory leaks or unexpectedly high loads.
By the way, Windows doesn't use pagefiles as "extra memory", it uses them as a backing store for private pages, just like regular files are used as a backing store for EXEs/DLLs and memory mapped files. So if the system really has more than enough RAM (like in your second screenshot, where you have 3.6 GB of free pages) you shouldn't see any reads from the pagefile. You can verify this by going to the Disk tab in the resource monitor and looking for any disk IO from pagefile.sys. On smaller systems that don't have an excess of free pages you may see periodic reads from the pagefile, and this is expected because the total amount of data referenced by the OS/drivers/processes is larger than the total RAM. Forcefully keeping all pagefile-backed pages in memory (which is what disabling the pagefile does) would simply mean some other pages (memory mapped files, DLL code or data etc) would have to be paged out.
Regarding further troubleshooting steps: If the system runs fine with a larger pagefile (commit charge stabilizes well below 80%, and you no longer see gigabytes of modified pages accumulating in memory) then you don't really need to do anything. If the problem persists, you can check for any processes with an abnormally high commit charge, and also check kernel memory usage in task manager. If it's a kernel leak you can usually narrow it down to a particular driver using poolmon.exe or kernel debugger.

Server 2008 R2 Memory Usage

We have 10 Server 2008 R2 servers all exhibiting the same behaviour.
The servers run at almost 100% memory utilization. Only one has had SP1 installed, which I did this morning and after about 1 hour, the memory is maxed out. The server initially had 14GB memory, but after installing SP1 and seeing more of the
same, I decided to try installing more RAM. I put in another 8GB, and while it takes a little longer to bottom out, it still bottoms out. Perfmon is showing less than 100MB of available memory, and, as expected, performance is not good.
These servers are strictly file servers. We work with images of hard drives. They are split into 2GB chunks. An easy way to replicate the issue is to load a hard drive image and do a re-acquisition. We do this sometimes as a drive
may be acquired in the field without compression, and we will re-acquire it with compression. Once this process is started, in about 1 hour, I have about 100MB free memory.
Using RamMap, Mapped File is using 21GB of memory. When I look at the file summary, the server is caching the 2GB image files and not letting go of them in a timely manner. I am the _only_ person accessing this server, it just gets worse
when more are.
As noted above, performance is terrible, is this supposed to be normal?
Server is an IBM x3550 M2 with dual quad-core CPU, 22GB RAM, OS is on a RAID 1 mirror of two 76GB 15K SAS drives, and the server has two 14TB arrays attached. OS is Windows Server 2008 R2 SP1. Only the File Server Role is installed.
Thanks,
Brian

Hi,
I would like to confirm that do you have Exchange Server installed on the servers?
If you do have Exchange Server installed, this behavior is normal. Exchange store.exe grabs as much RAM on the server as it can possibly get because
store.exe needs it to optimize performance. For more information, please refer to the following Microsoft TechNet blogs:
Why is Exchange Store.exe so RAM hungry?

Understanding Exchange 2007 Memory Usage and its use of the Paging File
http://blogs.technet.com/b/exchange/archive/2008/08/06/3406010.aspx
If you do not have Exchange Server installed, please check Task Manager and let us know what application uses the large size of memory. In addition,
you may run Process Explorer to monitor the memory usage. You may download and install it from the following link:

After that, please let us know the suspect.

Problem with scanning and memory usage

I'm running PS CS3 on Vista Home Premium, 1.86Ghz Intel core 2 processor, and 4GB RAM.
I realise Vista only sees 3.3GB of this RAM, and I know Vista uses about 1GB all the time.
Question:
While running PS, and only PS, with no files open, I have 2GB of RAM, why will PS not let me scan a file that it says will take up 300Mb?
200Mb is about the limit that it will let me scan, but even then, the actual end product ends up being less than 100Mb. (around 70mb in most cases)I'm using a Dell AIO A920, latest drivers etc, and PS is set to use all avaliable RAM.
Not only will it not let me scan, once a file I've opened has used up "x" amount of RAM, even if I then close that file, "x" amount of RAM will STILL be unavaliable. This means if I scan something, I have to save it, close PS, then open it again before I can scan anything else.
Surely this isn't normal. Or am I being stupid and missing something obvious?
I've also monitored the memory usage during scanning using task manager and various other things, it hardly goes up at all, then shoots up to 70-80% once the 70ishMb file is loaded. Something is up because if that were true, I'd actually only have 1Gb of RAM, and running Vista would be nearly impossible.
It's not a Vista thing either as I had this problem when I had XP. In fact it was worse then, I could hardly scan anything, had to be very low resolution.
Thanks in advance for any help

55%, it's still 1.6Gb....there shouldn't be a problem scanning something that it says will take up 300Mb, then actually only takes up 70Mb.
And not wrong, it obviously isn't releasing the memory when other applications need it because it doesn't, I have to close PS before it will release it. Yes, it probably is supposed to release it, but it isn't.
Thank you for your answer (even if it did appear to me to be a bit rude/shouty, perhaps something more polite than "Wrong!" next time) but I'm sitting at my computer, and I can see what is using how much memory and when, you can't.

BackgroundMediaPlayer high memory usage

Hi, I have a problem with WP8.1 Background task with BackgroundMediaPlayer. When I have just the simplest app, which have virtually zero logic in both the task and and app, when the task is started, it takes 15MB of memory. When playback starts, it jumps
to 21 MB, which leaves me about 4 MB (since the limit is 25 MB). This is just ridiculous. (I use MemoryManager.AppMemoryUsage to get used memory).
What I find even more stupid is the fact that when I run the app in emulator, the memory usage is 5 MB on start, after start of playback 11 MB. So I am left with 14 MB, which is ok.
I created a simple project, if you are interested, download it here: http://bezysoftware.net/files/App13.zip It will notify you about memory usage in background task using toasts.
Any ideas what to do? Beside rewriting everything in C++ - I already have an app ready in C#.

Hi bezysoftware,
Looks like emulator performs better than the real device? I'm not quite understand what do you mean by "playback" start, what's the difference between task start and playback start?
And sorry I cannot repro the issue on my emulator, always 7.7MB instead of 11MB as you mentioned.
I also tested with my Lumia 630, it only use 3MB when start and use 7MB when running, I cannot repro the issue.
I would also suggest you tell us what kind of device you are using, perhaps it related with the test device.

High RAM memory usage compared to other systems

I'm suffering with memory usage problems, only in open 2 tabs of facebook(it's only for example, any 'heavy' page freeze also) in firefox*(for example also, but this occur in chromium also) freeze computer.
I've 1GB of memory, it isn't big but also isn't very little.
I'm using XFCE with compiz (yes, compiz, since use a very lightweight openbox-based session doesn't help, then compiz...) when system start (after login) system is consuming 130MB approximately of RAM.
after 1 hour if close all open apps and see memory usage again consume is something about 350MB, "only solution" is reboot.
all applications(htop,free -m,xfce's system monitor...) that I've tried to monitor memory usage show above scenario, except the 'ps_mem' script in AUR.
in the 'ps_mem' script the result is following (with opera browser open, less memory offensive browser but I really prefer firefox):

as you can see in 'ps_mem' memory usage isn't nothing absurdly it's ok.
another example, this problem stop me make certain things, for example is impossible browsing in web while programming in eclipse, this is very uncomfortable.
other thing, this not occur in Windows XP, I can open more than 10 tabs in firefox, and eclipse open, etc...
any needing information, tell-me!
firefox*: with memory cache turned off in about:config

hotvic, could you please change the title to something more descriptive? 'memory problems' sounds like you have problems e.g. remembering / recalling things, which is not an Arch issue ;P

I've had some limiting performance with browsers lately (Firefox and Chromium). I found it had a considerable cache size utilizing lots of fragmented space on my home directory. I cleared the cache and have since set a limit to the cache size of 30 MB for Firefox. Between multiple users across multiple browser sessions, I had at least 2 GB of cache data on my 10 GB home partition! So far (1 day), this has been helpful. Perhaps this could help you also?

OP is talking about RAM, not HDD space.

How to analyse the main memory usage in SAP ERP systems?

Dear expert,
I'm doing a research work about analysing the main memory usage in SAP ERP systems.
I would like to find out what is load in buffers and when. That means, which process have the control of these memories and which are always performing something, tables loaded, and so on. Becuase I tried to isolate the space needed by a simple webservice call (create one material) in my test system, but even after a $SYN there are something stored in the buffers. I use a BAPI to avoid the execution of the SAPGUI and its repercussion in the system (I know the BAPI called uses resources too, but when I run this BAPI to get the statistics, it's like ST02, I get different values). Could someone help me or recommend something specific to read? Thanks a lot in advance.

Dear expert,
Thanks a lot for your answer. The point is now that I want to isolate the memory used by a webservice that I call, I mean, I would like to know how many memory is this webservice using in each buffer. And could you tell me where could I read something about the order that things happen in SAP System when a webservice is called (always memory related), that's which steps are done to store data in buffers and so on. Thanks in advance.

About the limitation of memory usage of Illustrator.

Please tell us about the behavior of the illustrator CS5/CS6 when memory usage of illustrator is too many.
The memory usage of Illustrator is increased, I think the application operates as follow.
- Warning display (e.g.:Illustrator can not preview)
- Illustrator stalls
1.Such as case, Is there memory usage limit?
2.In the case of memory usage of Illustrator exceed maximum size, how Illustrator works?
Is there a specification?
3.Is there the function of the memory auto-release in Illustrator?When the function work?

Thanks. Finally found where it is and turned off all alerts. Verizon doesn't make it easy to find where it is located. Appreciate the help.
