Does ReportDocument leak memory?

Using CrystalDecisions.CrystalReports.Engine.ReportDocument XI R2. w3wp.exe memory use raises while a report is generated (which is expected), yet it does not seem to be ever released after. If you keep generating same report again and again, IIS eventually runs out of memory. A report does not call any external DLLs or COM objects. Calling repDoc.Dispose() does not seem to help. Please help.

Methods:
Dispose()
GC.WaitForPendingFinalizers()
GC.Collect()
Details:
I created a C# application that connects to BOXI.
It does not specifically use the ReportDocument object, but was also encountering serious memory issues.
I was also using the Dipose method to mark objects for garbage collection.
.Net garbage collection happens automatically (at some time or another), but you can force it using GC.Collect(). I tried this, but was still leaking memory.
Until I found GC.WaitForPendingFinalizers(), which causes the garbage collector to wait until all disposed objects have completely finished their destructors. I think this made the difference with BOXI objects, because they are nested.
After I was using all three methods, I had no more memory issues. I realize this information may be out of date, but I posted it for future seekers.

Why does firefox leak memory up to 2Gb on windows7 64-bits on my Alienware computer but not on my 2 other Inspiron 6400 and 1750?

right now i have only 5 tabs open with information about firefox help firefox memory leak and so on just to try to see if i can find anything about why i have this memory leak and the memory leak is already up 1.3 Gb.

i have the same problem, please do something about it! I have 2gb RAM and after a few hours ff uses 80% of my RAM and additionally 1.5gb of virtual memory. This slows down ff, because of copying data from virtual memory to ram.
I know this is because of caching websites in RAM but it really slows down ff, here is my solution:
1. A user is able to specify maximum RAM to be used by ff
2. Website caches are sorted by last access datetime - now if firefox reaches the max RAM - it removes the oldest website from RAM.
Simple and effective. Damn it.

Why does Firefox leak memory after. I do the same operations in Firefox and Safari, Firefox in some cases uses over 500 MB of RAM, Safari uses about 50 MB

After opening and closing 5 windows in Firefox and Safari, at rest Firefox still claimed (approx.) 500MB of real memory, Safari return all memory and claimed only (approx.) 50MB at rest (all windows closed). My laptop starts over heating when browsing just simple information pages in Firefox. This still happens after updating to the latest browser.

Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

Why does Firefox 4 (4.0.1 specifically) leak memory?

'''Answer:''' I figured it out.
History lesson first. Ever since the 4.0.1 update, Firefox 4 has been crashing A LOT. It's gotten so bad that FF4.0.1 will eat memory with no end in sight and eventually Windows (Win 7 64-bit) forcefully close the program due to an out of memory error.
I have 8 GB of RAM installed. And, it would crash once it exceeds 1.5 GB of RAM used by Firefox 4. I've seen Firefox 4 go up to 1.85 GB of RAM in Task Manager. This is with 20 tabs open.
With the add-on Leak-Monitor, I've narrowed down the issue. Having only Leak-Monitor as the extension installed, all pop-ups point to how '''poorly Firefox 4 handles Javascript'''!
MSNBC Leak Monitor issue:
[http://www.octoberasian.com/tech/text/FF4-Leak-Monitor_MSNBC.txt Leak Monitor log from MSNBC.com]
I've gotten more pop-ups from even support.mozilla.com because of the Javascript on this website.
Firefox 4.0.1 is leaking memory from every Javascript on every website I load. It's leaking memory as we speak with only this page loaded (one tab).
FIX IT! Firefox 4 is poorly handling Javascript, especially when multiple tabs are opened.

octoberasian: I, too, am experiencing this phenomenon. I shut my system down, pulled the EIC cable, held down the power button - then replugged and rebooted. I closed down every unneeded application that I have set to auto-start. Finally, I opened a single Firefox 4.0.1 window and let it sit. It began with consuming 43 Mb of memory. By afternoon - about 5 hours later - it was up to 203 Mb. There is definitely something very wrong with this version. It does the same on all the machines we have, sans our server. We don't use the server for anything but being a server & it has some version of Firefox 3 on it anyway. No Java Scripts were running, nor were any Adobe ARM or any plugins. I noticed when plugins run - the memory leakage goes into overdrive. Hey, I'm just sayin'...

Leak memory in xerces DomParser

Does any one has a similar problem?
Thank you.

Skype 6.4 continues to leak memory at an astonishing rate? Hard crashes ALL my Macs

Last version of Skype 6.3 leaked memory like a river full of rapids. And once it gobbled up 1.5gigs or so of memory, it HARD crashed my iMac requiring a hard reboot. It only takes about 30 minutes for skype to do this. My iMac (2012 Core i7 3.4ghz 32 gigs RAM) is at Mac OSX 10.7.5 and it is repeatable every time. I have to set timers to remind me to restart Skype every 30 minutes.
We thought 6.4 would fix the issue but no luck doing exact same thing. My colleague is across the country on an iMac with 10.7.5 same issues. Repeatable on my Macbook Pro running 10.8. If he let's it run, he gets the black screen of death and have to hard restart. Just like me.
This issue has been around for several weeks and is making skype unusuable for us and we rely on it heavily. Note we are PAYING customers. to Skype.
This ONLY happens if we use the video feature. Submitted to Skype, wondering if anyone else having issue?

SystemUIServer leaks memory, possibly related to spotlight

SystemUIServer leaks memory. Immediately after reboot it occupies about 8 to 9 MB (real) on my system. Climbing to more than 17MB after only 30 minutes. After 3 days, 20 hours of uptime total real memory consumption of the SystemUIServer process was 441MB. Upon researching the process I found this forum devoted to Spotlight and interaction with SystemUIServer. Testing, I found Spotlight was unresponsive, the tool would not pull down and it didn't respond to the keboard shortcut.
Killing SystemUIServer brings the process memory usage back down but it continues to climb as it runs. Spotlight became responsive.
System is fully patched and updated.
I also noticed after rebooting from update that iSync logs messages like the following in console.log:
2007-08-09 05:54:54.180 SyncServer[3857] A Sync Server is already running on this computer, exiting process.

I guess my question would be, does anyone know when Apple is going to fix either Spotlight or SystemUIServer so it doesn't leak/crash as seems to so common here in the discussion groups?
Probably need a bit more troubleshooting...
My uptime is now 3days 20 hours -odd coincidence.
SystemUIServer is using 10.96MB Real Mem.
So, I don't know if I would expect Apple to already believe that there is a problem needing to be fixed. Really, don't think anything in this forum can be considered "common." For a core function of the OS, the Spotlight forum is now one of the quietest of all the Tiger forums- only one that sees less action is UniversalAccess.
Anyway, I'm not sure why you're having a problem with memory leaks in SystemUIServer or with Spotlight, and I'm not enough of a developer to tell you how you could debug it. All I can say is that your situation is not the norm and that there is likely something specific to your situation that is causing it. The unresponsiveness of Spotlight may very well be a side effect of the memory leak which is being caused by something else on the menubar.

How do you "pause" an open application, like Mac automatically does when the memory is full?

How do you "pause" an open application, like Mac automatically does when the memory is full?
I would like to do so proactively when I am not using a certain program but need to keep it open, and I want to free up computer resources.
In other words, I want to keep a given program open, but stop it from "thinking".

There is an application that I can only open a set number of times before it expires. Every time the program closes, you get one less use out of it. I want to use it as long as possible, so I thought I would just keep it open all the time. However, it consistently turns on the fan on the computer, so I imagine it uses a lot of resources. I got the idea after the Force Quit program "paused" it once after getting overloaded with all the apps I had open. It stopped the fan, and I was able to open it and run it again later with no problems. The tricky thing with trying to intentionally overload the system is that it's a hit or miss on which open program the OS will pause (to my knowledge).

Imapd service "Leak Memory"

I already have Java Communications Suite 6 Working , but, I have a Leak Memory problems with imapd process.
I have the server with 30 imapd process, 30 mshttpd process, and 30 pop process running to balance the load of the users.
All work fine(the CPU is 100% idle, the RAM is 80% available=6GB) when I access via browser(Chrome,Firefox), too when I access it with the traditional clients IMAP (Outlook, ThunderBird,etc).
The problem is that if one user want to copy(not just view) locally all your emails to your laptops/pc, the imapd process eat more than 3GB(instead of 80MB) of RAM and the system is getting slower.
If the user cancel this process(copy via IMAP all your emails) the process dont freedom doesn't release the memory and the system getting slower.
Actually my solution is:
# kill -9 <PID_imapd>
Some times when I kill the process the problem going to other imapd process, so in this case the solution is:
/opt/sun/comms/messaging/sbin/stop-msg
/opt/sun/comms/messaging/sbin/start-msg
I think that this problem is a bug but I dont know what is the patch.
May you help me? Any idea?
My system is:
A X2100 with one socket AMD Opteron 2600Mhz, 8GB RAM, 2 x disks 750GB in mirror with Solaris Volume Manager, Soalris 10 HW 10/08.
Thanks.

The rest of the imapd process(29) in this moment just load 40-50MB(when those are free).
If we kill the process 16673 the user connect to the next imapd process and the problem persist whit the same patology: eat memory and CPU, and slow the system.
So, we think that is not normal and maybe we need patch the system to solve the problem.
We will to test the 64Bit version in this moment and we will post the results.

Satellite Pro P100-327: memory card reader does not read Memory Stick Duo

I just got a P100-327
http://uk.computers.toshiba-europe.com/cgi-bin/ToshibaCSG/jsp/productPage.do?service=UK&PRODUCT_ID=121991&toshib aShop=true)
which, according to that page, is supposed to have "1 x 5-in-1 Bridge Media slot (supports SD Card, Memory Stick, Memory Stick Pro, MultiMedia Card, xD-Picture Card)" but the pdf user manual that came with it says that it does not support Memory Stick Duo, Memory Stick Pro Duo or mini-SD.
However, I have a Memory Stick Pro, and a Memory Stick Pro Duo in a Memory Stick Pro adapter and the reader can't seem to read either of them (they should both count as Memory Stick Pro which should be readable right?)
Should I be able to read my Memory Stick Pro cards? Why can't I since it says I should be able to? Do I need to install something first?

Hi
In my knowledge and according to the manual the Bridge Media slot supports Media of type
- SD Memory Card
- MultiMediaCard xD-Picture Card
- Memory Stick
- Memory Stick Pro
Please note that the Memory Stick and Memory Stick Pro are not the same as Memory stick Duo and Memory Stick Pro Duo.
Dont mix it.

DS 5.1sp2 SLAPI plugins leak memory

I am running DS 5.1sp2, on Solaris 9/SPARC, and have been encountering problems with the ns-slapd process leaking memory when using SLAPI plugins.
We have written our own bind pre-operation plugin function which, when enabled, causes ns-slapd to leak memory at a pretty rapid rate. I have a simple test where I perform a simple ldapsearch in an endless loop. The ns-slapd process starts off with a VSS of ~617MB (we have a fair amount of cache enabled) ; after a few minutes of my test, the VSS grows by several MB. With the plugin disabled, I can run the same test for hours with no growth in the VSS of ns-slapd.
I have also performed this test with my plugin disabled, and the "testbind" plugin function (the one provided in <server root></server>/plugins/slapd/slapi/examples/testbind.c) enabled. I see even more rapid memory leakage than with my plugin.
Are there known issues with SLAPI memory management? Is there anything I can do other than restarting ns-slapd on a regular basis (in production, this memory leak causes VSS growth of several hundred MB in the course of a few days).

I think if you want to modify the result before it is returned, your plugin needs to be invoked post-op as well. Your plugin can be both at the same time, just make sure your init function knows what to do when called a second time.
Moreover, without looking at the stack trace, it is hard to make any progress. Do you still have the core file? Can you paste the pstack and pflags output ?
# Run "file" on the core to see if its a 32 or 64 bit core
# cd /path/to/ns-slapd
# pstack <corefile>
# pflags corefile
Alternatively, see if you can reproduce the problem with a small plugin. Smaller the better. I'll give it a go.

GetOracleDecimal seems to leak memory?

Hello, I am using the C# statement below to retrieve a decimal value from an OracleDataReader, adjust the precision, then assign it to a .NET decimal type:
decimal volume = (decimal)OracleDecimal.SetPrecision(reader.GetOracleDecimal(5), 28);
Over time, the service that hosts this method leaks memory. After some investigation, I found that "Oracle.DataAccess.Types.OpoDecCtx" types were collecting in the finalize queue. Any ideas on how to resolve this? I can't explicitly Dispose() an OracleDecimal...
I'm using ODP.NET version 2.102.2.20.
Thanks

Thanks for the reply. I am using .NET 2.0 SP2. I upgraded the ODP.NET client to 2.111.7.20 but am still seeing leakage of the OracleDecimal structs.
Here's a snippet of output from WinDbg:
Ready for finalization 32874 objects (0b4de540->0b4fe6e8)
Statistics:
MT Count TotalSize Class Name
00fb8cec 32816 656320 Oracle.DataAccess.Types.OpoDecCtx
With each pass of the service the Count and TotalSize grow in increments equal to the number of rows I'm querying...
Just for laughs I changed the GetOracleDecimal statement to GetDecimal and the memory issue went away (because I'm no longer creating OracleDecimals). But I need to use the higher precision type to prevent overflows..
Thanks again..

When does java deallocate memory for objects;

um i'm working on a midp application that is very memory consuming. i would like to optimise it and make it just the oposite of what it is. now i would like to know when does java dellocate memory for an object, is it when it can find no more references to that object? or some other time, well i know its not when it can find no more references to that object because i've already tried that.
or to make things simpler is there any explicit way to make java deallocate memory for a specific object, like if i have a thread, which is executing a while loop, and i want java to end the thread and free its memory. is there any way to do this?

I happen to have quite some J2ME experience and it's not overly wise to count on extensive garbage collection. The garbage collector in limited device VMs isnt as advanced as it's big brothers. Try to avoid excessive object allocation and reuse instances whenever possible.
As for garbage collection, objects will be garbage collected if they can no longer be reached by any of the active application threads and if the garbage collectors deems it necessary to collect garbage, which will probably be when free heap memory becomes sparse or when there's some idle time in your application.

Flash is killing Safari, which is leaking memory ...

I just saw in Activity Monitor that the Flash plugin is using 147% of the CPU, with one Flash movie playing in one of 12 open Tabs
And Safari seems to leak memory as well, after a day or two it easily can use up to 3GB(!) of RAM.
I am now quitting Safari routinely every 2 to 3 hours to get the CPU usage down and free RAM for other stuff, but I don't think this method makes for a great user experience.

Hi,
Use ClickToFlash... that way you have control of Flash content.
