Memory leak for services.exe

Hi,
I have been observing memory leak for "Services.exe" process and which causes server hung issue. I am having server 2008 R2, hosting SQL server 2008 R2.
the handle count for services.exe rises to its limit quickly and the casues the server hung issue.

Hi,
I agree with Milos that you can install Process Monitor to find the root reason for this issue:
http://technet.microsoft.com/en-au/sysinternals/bb896645.aspx
In addition, it may caused by some corrupt event logs, please make sure you have applied the Maximum log size setting for event logs appropriately.
Best regards,

Memory leak in tagsrv.exe

I'm seeing a memory leak in tagsrv.exe on my laptop, where I use DSC
v8.2. When I close the screen (suspend the laptop), and then open
it again (resume), the tagsrv.exe memory usage jumps dramatically,
often to over 125MB. What is more, it appears each time I do this
the memory jumps again by this amount (I'm not completely sure how
consistent the incremental increase is, but I've often seen over 250MB
memory usage, and as high as 500MB). Has anyone else encountered
this, or does anyone have a solution?
Thanks.

Attached are some images of memory usage. Interesting, but the
problem does NOT occur if I simply hibernate then resume over a short
period of time. The images you see are the result of hibernating
OVERNIGHT. Not sure what to make of that. I did not have
LabVIEW running when the memory jump occured.
The LV DSC project I'm working on has about 40 shared variables, many
of which are supposed to be connected to a Modbus/TCP client via
OPC. However, during this development period I do not have the
hardware, so some shared variable errors result which I ignore.
Also, I'm using a dataset I/O server to create batch-oriented datasets.

Memory leak in oracle.exe and mds.exe

We are facing Memory leak in oue MDM server. Our environment details
are as follows;
MDM 5.5 SP5 ( Build 5.5.41.70)
Oracle 10.2 patch 2
windows server 2003 SP1
XI 7.0 SP 9
If server is running continuously 3-4 days then Nonpaged memory is
getting exausted and server does not respond. Now we have to retart the
windows server manually.
If we see the task manager it is shows more than 200,000 handles for
oracle.exe and more than 100,000 handles for mds.exe.
1: Oracle.exe -- more than 200000 handles ( Approx >5000 is problem)
2: Mds.exe -- more than 100000 handles ( Approx >5000 is problem)
Since these applications are not releasing the handles properly so all
nonpaged memory gets exausted and server stops responding.
If we restart the mdm server, database and OracleserviceMDMD, then
nonpaged memory is released. But some times even if we restart these
services, we do not get nonpaged memory released. So we have to restart
the windows server.
please help me if anyone else have faced the same problem.

Closing as question is answered in MDM forum.

2008 R2 - Memory Leak from svchost.exe - Module "rpcrt4" is the culprit

Hi All
Over the past week or so (after a set of Windows updates and restart) svchost.exe has increasingly used more and more memory. It probably gobbles up an extra 1GB per day and doesn't relent.
After running various diagnostics, the debug diagnostic tool finally provided me this information after a memory leak test:
rpcrt4.dll is responsible for 1.76 GBytes worth of outstanding allocations. The following are the top 2 memory consuming functions:
rpcrt4!AllocWrapper+2b: 1.76 GBytes worth of outstanding allocations.
rpcrt4!Ndr64ClientInitialize+964: 1.36 MBytes worth of outstanding allocations.

Can anyone help or advise as I cannot find any hotfixes for this issue.
Thanks
Ryan

Hi Ryan,
Please narrow it down to the specific service that is having the issue. That way you will know where to focus on.
For the specific svchost.exe that is showing the large memory usage, use task manager/process explorer/etc. to determine which service(s) are running within it. If there are multiple services running within it, I recommend you isolate them and then
restart your server. For example, say you determined that the following services are running in the "problem" svchost.exe: AudioEndpointBuilder, Netman, TrkWks, UmRdpService, Uxsms. You would open an admin command prompt and enter the following
commands:
sc config AudioEndpointBuilder type= own
sc config Netman type= own
sc config TrkWks type= own
sc config UmRdpService type= own
sc config Uxsms type= own
After entering the above commands you would restart your server for the changes to take effect. Over time you would monitor memory usage of the suspect services, and eventually it will become apparent which one is using too much memory.
Thanks.

Memory Leak in NK.exe

Hi All,
OS: Windows Embedded Compact 7 with updates till Feb 2015.
Hardware: AM335x based
Applications running: one serial port application and one tcpclient and tcpserver apps. all are managed (C#) applications
I am facing memory leak issue with our headless device.
When I connect the device to LAN network, memory usage keep increases and after few hour (some times <1 hour, some times 4-5 hour) devices go to hang state due to low memory.
I also tried to run the resource leak detector and found
1. NK.exe heap is increasing
2. on startup : API Handle Count = 4118, DuplicatedHandle - Count : 4,082, Size : 4,082 bytes
After few minutes: APIHandle - Count : 49,172, Size : 49,172 bytes, DuplicatedHandle - Count : 48,810, Size : 48,810 bytes
NK.exe heap increases as available RAM decreases.
our application heap is constant only. please find below memory snapshots taken by devhealth.
1. On device start up after all apps started
2. After 1 hour of device running. - refer attachment
where exactly might be this leak, any Guess?
Thank you...
rakesh

Hi tomleijen,
Thanks for your suggestions.
Even we tried without any user apps, then also we found ~1 MB increase in NK.exe heap every 30-40 min.
we have 2 images 1. with all WEC7 updates (Till feb 2015) and 2. without any of the WEC7 updates
almost same problem we are facing with both images.

Memory Leak on SpoolSv.exe

Hi
I have a Windows 7 x64 (Ultimate) running on my laptop. Weeks ago i started noticing weird errors like: "memory low", can not start virtual machine. I wasn't running special memory consuming programs. "A reboot a day keeps the troubles away" was my temporary workaround.
When i started digging into the problem, i noticed that memory usage of the process spoolsv.exe was rather high. I have a screenshot of my task manager showing that the "Private Working Set" and also Commit Size is very large.
In the meantime, I have read in another post about a general memory leak in Windows 7 where they suggested using the driver verifier, but it didn't gave me any clue. I uploaded the screenshot of the driververifier.
When the process is skyhigh in memory usage, i can kill it. But a few minutes later i have taken these screenshots from the process explorer.
1) SpoolSv is using CPU. Apparently it is not only consuming RAM but also CPU power.
2) spoolsv.exe graph
I am not printing, or have not printed since days (and several reboots).
Normally I wouldn't care about (temporarly) high memory usage, but it really never drops... Other programs do crash because the lack memory (like videodriver or skype).
Has someone any idea why this process slows down my pc and keeps getting bigger minute after minute?
Kind regards
Please click 'Mark as Answer' on the post that helped you.

Hi DamPee,
In addition, I would like to suggest you perform the following steps to check the issue.
Clear Printer Spooler Files and Restart the Spooler Service
=================================
1. Click Start, type "Services.msc" (without the quotation marks) in the Start Search box and press Enter.
2. Double-click "Printer Spooler" in the Services list.
3. Click Stop and click OK.
4. Click Start, type "%WINDIR%\system32\spool\printers" in the Start Search box and press Enter, delete all files in this folder.
5. Click Start, type "Services.msc" (without the quotation marks) in the Start Search box and press Enter.
6. Double-click "Printer Spooler" in the Services list.
7. Click on Start. In the Startup Type list, make sure that "Automatic" is selected and click OK.
What’s the result?

Will the memory leak for queue when used in producer and consumer mode in DAQ to transfer different sized array.

In the data acquisition, I use one loop to poll data from hardware, another loop to receive the data from polling loop sent by queue.
But everytime the size of the transferred data array may not be the same, so the system may assign different array size and recycle very frequently.
Will it cost memory leak. Or will it slow down the performance, since the array size is not fixed, so every time need to create a new sized array.
Any suggestion or better method.
Solved!
Go to Solution.

As i understand your description, your DAQ-loop acquires data with the setting '-1' for samples to read at the DAQmx read function. This results in the different array sizes.
Passing those arrays directly to a queue is valid and it does not have significant drawback in performance (at least as far as i know) and it definetly does not leak memory.
So the question is more or less:
Is it valid that your consumer receives different array sizes for analysis? How does your consumer handle those arrays?
hope this helps,

IE Memory Leak for addCallback

Everytime I register:
ExternalInterface.addCallback("reload",reload);
or any other ExternalInterface.addCallback
I see memory leaks. Even if its not called. Does anyone know how to mitigate this?
Also, I can't seem to get flash to release it's memory unless I close IE. Is there another way? I've already tried removeAll in extJS but it doesn't seem to work. The element is removed but the memory is still being used.
thanks
Pascal

I believe that bug has not been fixed yet. I don't know of any workarounds
for the main app. For child SWFs, proxy all calls through the main app.
It also looks like you're trying to reload, but you might be better off
resetting the app.

Memory Leak for Graphics2D.drawString?

Hi, all!!
I am a Java Programmer who is experienced in Swing application on a windows platform.
I have developed a code snipplet to print out to use Graphics2D.drawString method.
Then, I have encountered the performance degrade that the number of objects are created per call for the method.
It seems that there is a difference among JDKs.
When such a method is called, the number of objects are created is the followings
Java1.4 | 138
Java5 | 946
Java6 | 1217
Is this a known bug that JDK has since JDK has changed graphically from Tiger?
or is it related to memory leak?
Thank you in advance

Memory leak in solaris 9

Hi ,
I have Oracle9i database running on Solaris 9. After every 6 days my solaris box went out of space although its a test box and there is no activity on the system. Why the hell it takes all the ram and swap space when there is no activity on the system except Oracle Instance is running with no user connection. What process are running in the background that takes all the memory and i have to restart this box every week. IS THERE ANT PATCH OF MEMORY LEAK FOR SOLARIS9?. I am not a solaris administrator and i have to fix this problem before moving my system to production. I would really appreciate your help.
Thanks.

Hi ,
I have Oracle9i database running on Solaris 9. AfterI have had for some months been running oracle 9i (and 8i) under solaris 9. There have been no problems and the server has been stable.
It sounds like you may have misconfigured the solaris kernel. It also sounds like your SGA is too large to fit in memory.
So I guess the first step would be to check the SGA and then the /etc/system file.
Here is what mine looks like for example:

Memory leak issues persist in Safari 6.0.5 (it's about time that Apple actually fixed this)

Safari has been notorious for its memory leaks for years, as I'm sure many of you know. I stopped using Safari as my main browser in 2010 or so, and I instead began to use Chrome. However, I recently had to use Safari to access some webpages, and I neglected to quit out of it. A few hours later, my computer slowed to a complete crawl. I was confused, because my computer never slows down to such a crawl, so I went into Activity Monitor to find the 'Safari Web Content' process using all of my available RAM, which was nearly 6 GB. Needless to say, Safari was force quit after that. I've heard that some plugins will cause this, but Flash was my only active plugin. Flash is, indeed, a heaping pile of crap that will readily eat resources as it sees fit- but this never happens to me in Chrome, and I use Flash all of the time n Chrome. This was after it had been sitting idle for quite some time, and I imagine that it would have used more RAM if it could.

Using 6.0.5 here without any of those issues ...
Regardless of whether Flash is being used, from your Safari menu bar click Help > Installed Plug-ins.
Try troubleshooting extensions and third party plug-ins.
From your Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that off if there are any installed. Quit and relaunch Safari to test. If that helped, turn extensions back on then uninstall one a time to test.
If it's not an extensions issue, try troubleshooting third party plug-ins.
Back to Safari > Preferences. This time select the Security tab. Deselect: Allow all other plug-ins. Quit and relaunch Safari to test.
If that made a difference, instructions for troubleshooting plugins here.
my computer slowed to a complete crawl.
Checked to see exactly how much space is available ??
Click your Apple menu icon top left in your screen. From the drop down menu click About This Mac > More Info > Storage
Make sure there's at least 15% free disk space.
Checked the startup disk lately?
Launch Disk Utility located in HD > Applications > Utilities
Select the startup disk on the left then select the First Aid tab.
Click: Verify Disk (not Verify Disk Permissions)
If the disk needs repairing, restart your Mac while holding down the Command + R keys. From there you can access the built in utilities in OS X Recovery to repair the startup disk.

Oracle JDBC Thin Driver Memory leak in scrollable result set

Hi,
I am using oracle 8.1.7 with oracle thin jdbc driver (classes12.zip) with jre 1.2.2. When I try to use the scrollable resultset and fetch records with the default fetch size, I run into memory leaks. When the records fetched are large(10000 records) over a period of access I get "outofmemory" error because of the leak. There is no use increasing the heap size as the leak is anyhow there.
I tried using optimizeit and found there is a huge amout of memory leak for each execution of scrollable resultsets and this memory leak is propotional to the no of records fetched. This memory leak is not released even when i set the resultset,statement objects to null. Also when i use methods like scrollabelresultset.last() this memory leak increases.
So is this a problem with the driver or i am doing some wrong.
If some of you can help me with a solution to solve this it would be of help. If needed i can provide some statistics of these memory leaks using optimize it and share the code.
Thanks
Rajesh

This thread is ancient and the original was about the 8.1.7 drivers. Please start a new thread. Be sure to include driver and database versions, stack traces, sample code and why you think there is a memory leak.

Finding Memory leaks in C using Visual Studio 2013

I am using Visual Studio 2013, and taking a course in C programming and we started
talking about memory bugs detaction, in particular memory leaks, and how to detect them using Valgrind on Linux.
I want to know if there is a way to detect such memory leaks using VS 2013. I tried searching online but it just leads to lots of articles and blogs and msdn posts and blogs with lots of words like dump files, and analyzing them, etc which is weird
because:
1) It sounds so complex, convoluted and unintuitive it is actually hard to comprehend it.
2) The main reason this is weird is due to the fact that VS is the most advanced IDE around and Microsoft spends so much money on in, yet from what I have read it seems that there is no simple way to use VS to detect memory leaks
- certainly no way that's as simple as Valgrind where I only have to compile the program and run the command valgrind -leaks-check=yes ProgramName
and it simply prints to me all location it thinks there is a memory leak and describes the error (like not freeing memory after allocating it with malloc hence having "dead" memory after the program finishes, or accessing memory that's out of
the array bounds)
So my question is how to use VS 2013 in order to achieve the same results and to find out First in high level if there are memory leaks in the program, and Second - to detect in a simple manner where those leaks are- preferably without involving dump files
(not that I know how to use them anyway in VS).

Hi MicrosoftLaw,
Thanks for your post.
Based on your issue, if you want to check if there are memory leaks in the C program from this VS2013. I suggest you could try to find Memory Leaks Using the CRT Library, for more information:
https://msdn.microsoft.com/en-us/library/x98tx3cf.aspx?f=255&MSPPError=-2147217396
In addition, I find a similar thread about this issue, please you refer the Dusty's suggestion to check this issue.
http://stackoverflow.com/questions/45627/how-do-you-detect-avoid-memory-leaks-in-your-unmanaged-code
I did some research about this issue, I found that the Visual Leak Detector extension tool is a free, robust, open-source memory leak detection system for Visual C++. So if possible, I suggest you could try to use the Visual Leak Detector extension
tool to find the memory leak for Visual C/ C++ program.
https://visualstudiogallery.msdn.microsoft.com/7c40a5d8-dd35-4019-a2af-cb1403f5939c
However, if you have any issue about how to use this Visual Leak Detector extension tool to find the memory leak for C program. I suggest you could directly to write a review to this REVIEW tab in Visual Leak Detector site.

Memory leaks in JDeveloper?

Hi,
I have created two entity objects for two tables in Oracle database. In windows task manager, I started watching the memory usage for "jdevw.exe". When I keep clicking back and forth on the two entity objects in the navigation window, I see that the memory usage going up with every click. I watched it going from 70MB to 130MB until I stopped clicking.
Is this a known bug?
Product: JDeveloper 10G (preview version build 1375)
OS: Windows 2000 w/512MB RAM
DB: Oracle 8.1 running on the same PC
Hope it helps.
Raju

I have the same problem. I am using ADF with JClient, locally deployed.
And I have also noticed that after approx 5 or 6 commits (i.e. when I insert a new record, enters its values and then commits, and repeats these steps 5-6 times) the memory consumption is radically increased and finally the computer is running out of memory.
I really hope that these problems will disappear in the production release of JDev 10g.

Hi,
the screenshot does not indicate a memory leak. Memory leaks show by the server memory consumption that leads to slow performance or stale applications. Your issue seems to be different from that and doesn't really explain in the screen shots. If you have a support contract then customer support is the recommendation I like to give
