Memory leak in "get property value (string)" ?

Hi,
I'm not sure which forum to post this to because it involves a combination of labview and teststand. The error I'm getting is more teststand related so it is here.
In our application, we have a labview queued state machine launched by a teststand step using "launch vi asynchronously". In one of the states of this state machine, we are looping grabbing frames from a camera, querying a teststand using "get property value (string)", to overylay on the video on each frame. This is so when we post process the video, we can tell what step(s) teststand was performing (we are writing a status string to a property from teststand as well). Since this string has to be overlayed on the video for each frame to be visible when played back, this happens many many thousands of times over the multi hour test runs of the platform.
My problem is, after 22 hours or so of running, I get an error generated from the "get property value (string)", saying cannot create any more threads. The only thing wired to this tool in our vi is sequence context, which is passed in when the vi is launched from teststand. When opening the "get property value (string)" vi itself, it is very simple, consisting of a "aspropertyvalue" casting, reading of the string from the proprety, closing the aspropertyvalue reference, and exiting. It does not seem like there should be any "threads" being created here, except for perhaps the vi itself executing. But in that case I would assume the OS itself would clean up after itself.
BTW, the OS I am testing on is win7 x64. I did see this though running on our xp box once as well though, same amount of time. It is very repeatable. My next plan is to disable this get property value using a disable case, and run again, but I"m still wondering why this error is occurring. Any help or insight will be appreciated.
Thanks

Hi David,
Have you tried just using property node | Method Nodes instead of using the VI. There should be no difference but I think that VI is polymorphic ie the input with change depending on what's wired to it eg string, double etc.

I am getting a hibernate exception error
HibernateSystemException: exception getting property value with CGLIB
does anyone know what it means?

check the setter method for the property LANG_CD in com.dst.fourx.model.codeModel.CodeGroupDisplay.
it must be like -
setNlsLanguage(CodesGroup xyz) { ... }
The paremeters must be objects, not the type of the database column. We can specify the actual field in CodesGroup which acts as the foreign key in CodeGroupDisplay in the "property-ref" attribute of <many-to-one> element in the mapping file for CodeGroupDisplay.
This worked for me. Hope it works for you too.

How works Get Property Value / Type Automatic?

Hi,
I need to get in Labview some variables from Teststand. The VI I wrote use "Get Property Value" from Teststand and works fine... when I specify the type of variable I whant from Teststand (Boolean, I32,...).
But I need a VI which retrieve the value of my variable independently of the variable type.
I tried to set the type option "Automatic" but the "Get Property Value" always give back an empty array of boolean....
How works the "Automatic" option by the "Get Property Value"?
Is there a possibility in Labview to get the type of a Teststand variable?
Cheers,
Risotto

Risotto,
the "automatic" feature is no feature but an entry made because of the
polymorphic design of the "get property value" VI. if you would change
the order of the VIs contained in the polymorphic VI, you would
retrieve other kind of values.
therefore never use the automatic setting of this VI. the
simplest way to solve such thing is to pass the data in variant and an
additional numeric value for identifying the type of the value.

ADO memory leak when getting Recordset from an Oracle stored procedure?

I am programming in C++ (VC 6) and using ADO 2.7 to
access Oracle 9i database. My connection string looks
like this:
Provider=MSDAORA.1;Persist Security Info=True;User ID=scott;Password=tiger;Data Source=blahblah
I have Oracle stored procedure that returns data in a
REF CURSOR output parameter. Since the stored procedure
takes input parameters, I prepare a Command object with
Parameters initialized and attached to it. I use the
Recordset Open method to execute the call. This approach
works because I get correct data back from the call in
the Recordset, but the problem is when I do this in a
infinite loop and watch the process in Windows Taks
Manager, I see 4k or 8k memory delta all the time and
the Peak Memory Usage of the process keeping going up.
I hope someone knows something in this scenario and points
me to the right direction.
Thanks, please see the following code for specifics.

Whenever large numbers of BSTRs are allocated and freed quickly the process memory will continue to climb towards a stabalizing value. BSTRs are not freed until the system frees them. You can see this by making many calls allocating and freeing BSTRs, memory will climb, but when you stop for a while the gargage collection of the sys strings will take place. I've done much research to see that a server doing many queries very rapidly is not leaking memory, but out pacing the garbage collection, it will stabilize and when the process has some "rest time" the processes memory usage will decline.
In my research a suspected memory leak was not one.

How to Get property values from Shared Object in client's load event - Very urgent

I am using shared object to share data between two users. First user connect to shared object and set some value in shared object. Please consider that second user has not connected with the shared object yet.
Now when second user connects to the server and try to get that property set by first user, he could get shared object but could not get properties of Shared object set by first user. I observed few times that Second user can get these properties within "Sync" event between two users. But I would like to get these values for Second user in any stage (i.e. in load event etc.). Whenever Second user tries to get the property of Shared object, the object will reset the actual property value and then return reset value.
Anyone faced such issue while using shared object between two users. If so, I would appreciate if you could let me know your suggestions for following questions:
1) Is there any way to get all the properties of shared object before sync event called, as I want to get it immediately when second user connect to the application and perform next task based on the values stored in shared object.
2) Is it possible for second user to check whether any property has been set by first user? So that second user can use the property instead of reset it.
Any kind of help would be greatly appreciated.
Thank You.

You have problem because the batch size property has value *10000* and amount of records(*50000*) bigger than this value.
You can retrieve workaround from my post (OracleBulkCopy have memory leak if BatchSize is less than record's count.

Version 7.3 memory leaks Windows 8 then crashes

Hello, There are already some threads about this, but they mention Windows 7. I can confirm the memory leak (it gets up to 1.5 gb then crashes) is happening on windows 8 and windows 8.1. This issue wasn't present for skype 7.2.0.103 , it is present for 7.3 and also for 7.4.0.102 . It leaks for about 0.6MB per second , it constantly writes to disk 0.3 MB/S and uses ~12% CPU. This behavior happens only after I'm logged in. No calls, no messages, just staying logged in is sufficient. Furhtermore, the memory leaked by Skype is not returning to the system, so I end up having 75% memory used on a 16 GB machine after restarting skype several times (because it crashes and I need skype to communicate with my contacts constantly). Please provide me with a link to download 7.2 (since it works). I had this issue with Skype 7.3 and in 7.4 nothing got solved, so please give me a link to something that works rather that something that's shiny but broken. Thank you

The memory leak is still occuring in 7.6.0+.
Downgraded to 7.2.0.103 and it still does not prevent memory leak. Eventually it crashes around 1100MB of RAM usage on my system. Validated everything is working like directx, etc. I think this is a Microsoft Windows 8.1 bug, and not just a Skype memory leak issue, as I have seen one other application do the exact same thing (grow to 1100MB and crash). Time to go bug Microsoft for a solution... oh wait... Skype is a Microsoft product.

Mdx get properties value

Hi Expert
I have a mdx:
with member
[PLANITEM].[H1].[ccc] as
'[time].[h1].currentmember.properties("DAYS")' ---> this one cannot get property value
member
[PLANITEM].[H1].[aaa] as
'[time].[h1].currentmember.properties("level") --> this one ok .....
What I want to get is the current month days for further calculation. In my TIME dimension already include properties("DAYS")'
I am just can get all other PROPERTY value , EXCEPT property "DAYS" .why??
any idea??
Thanks..

Go into Admin...Click on the Dimension, then do Maintain Dimension Properties....and make sure that the "InApp" box is checked next to the "DAYS" property.
You will need to then process the dimension since it is a structural change. Full process.
Please let me know if this resolves your issue.

"Property value is not valid" when PropertyGridView tries to convert a string to a custom object type.

Hi,
I have a problem with an PropertyGrid enum property that uses a type converter.
In general it works, but when I double clicking or using the scoll wheel, an error message appears:
"Property value is not valid"
Details: "Object of type 'System.String' cannot be converted to type 'myCompany.myProject.CC_myCustomProperty."
I noticed that the CommitValue method (in PropertyGridView.cs) tries to convert a string value to a CC_myCustomProperty object.
Here is the code that causes the error (see line 33):
(Using the .net symbols from the PropertyGridView.cs file)
1
        internal bool CommitValue(GridEntry ipeCur, object value) {
2
3
            Debug.WriteLineIf(CompModSwitches.DebugGridView.TraceVerbose,  "PropertyGridView:CommitValue(" + (value==null ? "null" :value.ToString()) + ")");
4
5
            int propCount = ipeCur.ChildCount;
6
            bool capture = Edit.HookMouseDown;
7
            object originalValue = null;
8
9
            try {
10
                originalValue = ipeCur.PropertyValue;
11
12
            catch {
13
                // if the getter is failing, we still want to let
14
                // the set happen.
15
16
17
            try {
18
                try {
19
                    SetFlag(FlagInPropertySet, true);
20
21
                    //if this propentry is enumerable, then once a value is selected from the editor,
22
                    //we'll want to close the drop down (like true/false).  Otherwise, if we're
23
                    //working with Anchor for ex., then we should be able to select different values
24
                    //from the editor, without having it close every time.
25
                    if (ipeCur != null &&
26
                        ipeCur.Enumerable) {
27
                           CloseDropDown();
28
29
30
                    try {
31
                        Edit.DisableMouseHook = true;
32
/*** This Step fails because the commit method is trying to convert a string to myCustom objet ***/
33
                        ipeCur.PropertyValue = value;
34
35
                    finally {
36
                        Edit.DisableMouseHook = false;
37
                        Edit.HookMouseDown = capture;
38
39
40
                catch (Exception ex) {
41
                    SetCommitError(ERROR_THROWN);
42
                    ShowInvalidMessage(ipeCur.PropertyLabel, value, ex);
43
                    return false;
44
I'm stuck.
I was wondering is there a way to work around this? Maybe extend the string converter class to accept this?
Thanks in advance,
Eric

Hi,
Thank you for your post! I would suggest posting your question in one of the MS Forums,

How can I get the value of a custom property from a resource object?

I am trying to get the value(s) of a custom property, called "status" within a method. The method has an object of type IResource available to it.
I have tried the following:
PropertyName propName = new PropertyName("","status");
value = res.getProperty(propName).toString();
However, I am getting a NullPointerException when I try to create the PropertyName instance.
Is there a better way to get the value of a specific property from a resource object?
Thanks,
Tom

Thanks Praveen.
I was missing the default namespace of "http://sapportals.com/xmlns/cm" - I thought I could just pass an empty string for the namespace, but it looks like I must always specifiy, even if it is default.

Memory leak in string class

We have developed our application in Solaris 10 environment. While running Purify on that it shows leak in the string class. This leak is incremental and so process size keeps in increasing. If we replace string with char array, the leaks disappears and process size also becomes stable.
Following is the snapshot of the memory leak stack reported by Purify:
MLK: 4505 bytes leaked in 85 blocks
* This memory was allocated from:
malloc [rtlib.o]
operator new(unsigned) [libCrun.so.1]
void*operator new(unsigned) [rtlib.o]
__rwstd::__string_ref<char,std::char_traits<char>,std::allocator<char> >*std::basic_string<char,std::char_traits<char>,std::allocator<char> >::__getRep(unsigned,unsigned) [libCstd.so.1]

std::basic_string<char,std::char_traits<char>,std::allocator<char> >&std::basic_string<char,std::char_traits<char>,std::allocator<char> >::operator=(const char*) [libCstd.so.1]
Has anyone faced this problem earlier or is there any patch available for this?

Over time, we have found and fixed memory leaks in the C++ runtime libraries.
Get the latest patches for the compiler you are using. (You didn't say which one.) You can find all patches here:
[http://developers.sun.com/sunstudio/downloads/patches/index.jsp]
Also get the latest Solaris patch for the C++ runtime libraries, listed on the same web page.
If that doesn't fix the problem, please file a bug report at

with a test case that can be compiled and run to demonstrate the problem.

How to get the 'text' property value of a button in coding?

Hi Experts,
I'm using 10 buttons all are having common action('click'). when i click a button the 'text' value of the button should pass to a function.So the action is same but the passed value will be the 'text' value of the corresponding button. I don't know how to get the 'text' property of a button in coding. Kindly help me to solve this problem.
Thanks and Regards
Basheer

Hi,
My event is like this.
public void onActionclick(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
     String s = ? ; // should get the 'text' property of clicked button
     fillInput(s);     // function to be called
The called function is,
public void fillInput( java.lang.String id )
    String str=wdContext.currentContextElement().getNum();
    str = str + id;
    wdContext.currentContextElement().setNum(str);
How can i get the 'text' property value of the corresponding button. Click action should be common to all buttons.
Thanks and Regards,
Basheer

Memory leak in String(byte[] bytes, int offset, int length)

Has anyone run into memory leak problem using this String(byte[] bytes, int offset, int length) class? I am using it to convert byte array to string, and I am showing memory leak using this class. Any idea what is going on?

Hi,
If you post in Native methods forum I assume you are using this constructor in the native side.
Be aware that getting char * from jstring eats memory that you must free before returning from native with env->ReleaseStringUTFChars().

now if any body can help me removing this memory leak or is this the problem of OCCI
apparently it seems to be OCCI's library issue but i could be wrong please help
hoping to see a response

===================================================
this is not the same program but still this program gives the same amount of memory leak, this memory leak is reported in each program that uses OCCI
this program was made with the help of the sample program posted at the OTN website

hoping for a reply soon

How to get the iView Property value in NWDS

Hi all,
I my requirement I need to get some of the iView Property Value in NWDS.
Can anybody help me for this?
Helpful answers will appreciate.
Thanks & regards,
Kathiresan R

Steps
1. Define the properties in portalapp.xml
<component-profile>
<property name="user" value="asterix">
<property name="personalization" value="dialog"/>
<property name="plainDescription" value="User name"/>
</property>
</component-profile>
2. Within the doContent(request is a signature in doContent) method of your AbstractPortalComponent please
add the following code to access the property:
public void doContent(IPortalComponentRequest request, IPortalComponentResponse response)
IPortalComponentProfile profile = request.getComponentContext().getProfile();
String Name = profile.getProperty("user");

Memory leak in "get property value (string)" ?
