Fatal Internal Error : "objheap.cpp", line 579 - Labview 7.1 running on vista

Hello,
I was developing a project in Labview 7.1 and had saved it on vista when the vista OS decided to enter suspend, Labview 7.1 stopped responding as a result and I had to reboot. I will never trust vista again but when I try to open the VI I get the following error:
Fatal Internal Error : “objheap.cpp”, line 579.
And the following text file report is created. What I am wondering is there any way to restoring or uncorrupting this VI which is attached. Sub VI’s are not included but if you can get the VI to open even without them then the problem is sorted.

Hello Paul,
I have been looking into your error code as well as the attached files of your VI and LLB. Pasting in your error code is proving very helpful in trying to help you. I initially tried to open your files in my system, where I would possibly be able to resave them for you, however it looks like I will have to try a different approach.
As I understand it, you have been using LabVIEW 7.1 Full Development System with Windows Vista. LabVIEW 7.1 was released during the years when only Windows 2000 and XP were available. With the release of Windows Vista in later years, National Instruments produced LabVIEW 8.2.1 with support for Windows Vista Business or greater.
Please reply with the following information:
Are you using Vista 32-bit or 64-bit?
Are you still able to open the LabVIEW Development Environment to produce new VIs?
Have you tried to open other VIs (after backing them up) with LabVIEW 7.1?

Fatal Internal Error: "Memory Manager.cpp", line 547

Hello,
I am using LV 2009 and I am also getting an error as follows:
=======================================================
Fatal Internal Error: "Memory Manager.cpp", line 547

You will lose any unsaved work. For assistance in resolving this problem, please relaunch LabVIEW, or contact National Instruments.
=======================================================
I get this error when I start executing steps on TS 4.2.1 as well as when I do "Unload All Modules" in TS. Please find the attched logs. Further, I could not run anything in TS and need to restart the PC to re-run the sequence after everytime this error occurs.
We have transited through LV 8.0, 8.2, 8.5 and now 2009 over past 4 years for our project and this is the first time I could see this error.
Please help.
Thanks.

Adding on to Pritam's post:
For the earlier "Fatal Internal Error: "Memory Manager.cpp", line 547" , we found that a couple of our dll's which were developed in LV 8.5.1 had not been recompiled in LV2009. After recompiling each of them in LV2009, and then running the same sequences in TestStand,this error vanished.
But now again we're seeing this error, and that too only on 3 PCs systems out of 5 PCs!
The same installer has been installed on all 5 sytems (after removing the earlier installers and running MSI Blast.exe them).
The error now appears again, only when we try to exit TestExec.exe and another tool built in LabVIEW.
So everything works fine and tasks are performed,etc, but when we close the window or try the exit that program, the "Fatal Internal Error: "Memory Manager.cpp", line 547" pops up.
If we say "OK" to it, the window closes, but the Task is seen still running in the Task Manager and has to be manually terminated (End Task).
Does anyone know what could be going wrong?

Can somebody fix my corrupted subvi, error "Fatal Internal Error" "objheap.cpp"

Hello,
I have been strugling to open this file after a reboot due to not responding computer. The file is a part a larger library however, this is the part that is not responding and giving "Fatal Internal Error" "objheap.cpp" .
Does anyone know how to fix this issue or how to repair this file.
I am using a LabView 2012.
Thank you for your time.

Hi obarriel,
that could be a tricky job as LV2013 claims "block diagram can't be opened"!
Meanwhile you should learn two things:
- using LLBs isn't recommend practice nowadays (atleast not for storing daily work VIs)
- make a backup of your works on a regular basis (using SVN/GIT is recommended too…)

Has anyone else had this issue? What needs to be done to fix this.

Hello,
This was reported to R&D (#4ALB7O89) for further investigation. Are you able to reproduce this problem with the same VI? Are you able to build an application with a simple VI?

Fatal internal error: memorymanager.cpp, line 566

Hello all
I have been seeing this error sicne recently, when I run a test sequence in TestStand 2010 SP1, f1. I call dll made in NI LabVIEW 2010 SP1, f4.
I had been using this test sequence and dll functions since almost two months. but its just since last couple of days that I receive this error.
I also get a TestStand execption and then the TestStand would crash. the reason why I am posting it here is because, when I do not run the step which has this dll call, I do not get the error. My entire tests runs over days. As soon as I include this dll call in the test, I keep getting this error.
Along with this MemoryManager error, I also see "TestStand Exception" and "TestStand has to close due to an error".
The dll function has been developed using LV 2010 SP1. That is a monitor VI whose front panel will be opened using dll call. I pass a test file name using the dll calls and then the VI will open the TDMS file and display the data till I click Stop.
this TDMS file is being written into, inside a datalogging dll which is also launched from TestStand. This dll is also developed in LabVIEW by us.
I have been using this setup since weeks and now I get this error. Also, I get this after I had upgraded both TS and LV to the latest fixes (f1 and f4).
But the help for this error on NI website actually says we should upgrade to the latest fix inorder to avoid this error!!
I will post this also on the TS board.

Same error. TestStand 4.2.1 calling LabVIEW 10.0.1 (2010 SP1).

Fatal internal error: I/EX

I am developing an application, it will read out data in an olite db(5.0.2.7) using jdbc call, then it will write these data into an oracle 9i db using bc4j.
my system runs in win xp, I am using JDeveloper 9.0.3.1035.
when I run my class as a plain java application, everything is ok.
but when I call my class from a servlet as a web applicaiton, the web application terminate unexpected with an popup error message:
I/EX 311, and I can find this error in log:
Fatal internal error: I/EX
When I debug my program, I found that the error occured in rs.getString() statement :
ResultSet rs = ... ;
String s;
s = rs.getString("...");
Any one can help?
thanks.

Hello ! I am working with Oracle lite :
Connected to: Oracle9i Lite ORDBMS
Database Name: POLITE (Read Write)
Database Version: 4.0.2.0.0
Auto Commit: off
Driver Name: oracle.lite.poljdbc.POLJDBCDriver (OLite 4.0)
and Jdeveloper 9i
JDK 1.3 of the Jdeveloper and W2K Professional
I was searching for an answer cause I have the same problem but I realized that the problem is not directly related with BC4J or OC4J.
I suspect that is involve with the driver olite40.jar I hope you can validate this. I can reproduce the problem and it happen when you run a program in an application Server , I tried with OC4J and Tomcat the code like Weijun Tian explain I show two examples :
1st case : Supouse that I run a query to database like that : select name, price from tableTest ;
Statement stm = con.createStatement();
ResultSet rs = stm.executeQuery(�select name, price from tableTest�);
If the column �name� doesn�t exist or is incorrect writed I expect a SQLException well , that is right if I run a simple program with main method. But if I run the same query into a servlet , I have the problem of Fatal Internal Error I/EX without any explanation. This is running in OC4J now, if I run in Tomcat the same code I obtain :
Unexpected Signal : EXCEPTION_ACCESS_VIOLATION occurred at PC=0x6d442b44
Function name=JVM_DisableCompiler
Library=C:\jdk1.3.1_09\jre\bin\hotspot\jvm.dll

at com.next.jsptest.Product.getDetail(Producto.java:59)
at com.next.servlets.ControlServlet.doPost(ControlServlet.java:163)
�.
�.
In both of them (OC4J and Tomcat) the server is shut down after the problem.
2nd Case : Now, suppose another situation , imagine a field in the database that is null , well, after the rs.getString(�THE_FIELD�), I expected that the answer will be null ok, if I run this in a simple class with main method there is no problem but if I run the same in a servlet , well, the same problem! I/EX and server shutdown again with OC4J or Tomcat, the same problem.
I think that something like that happen with you Weijun Tian.
Well , what I think is that there is a problem with Oracle Lite to work with application servers, I don�t understand why works fine in simple programs with main method but when I run in a server the same query have these kind of errors , I really hope you can help me because I don�t want to tell that Oracle Lite doesn�t work with an application server or is not a good Database for web applications.
Thanks a lot!!!
PD . I also put here my posts to the metalink and forums.

Hi there, I have the same problem but I found that there is not directed relation with the getString(),the problem is in general. Apparently the driver does not work with SQLException , for example I try to make update and I put a column that not exist I expected a SQLException but get the error Fatal internal error: I/EX and the server shut down (?).
I think that it dependes of the driver, I am using OLITE4.jar in windows 2000 and works fine but when I have a simple error (talking about JDBC) get the error I/EX and shut down the server. Could you help me with some advice around this??
21 / 10 / 2003
Also I found that when I use the driver in a simple program the SQLException is captured for the try-catch block but when the same query for example is running in the JDeveloper from a servlet using the server for test of JDeveloper the same exception produce the problem of Fatal internal error:I/EX , I tried the same code in a Tomcat server and this is what I get :
Unexpected Signal : EXCEPTION_ACCESS_VIOLATION occurred at PC=0x6d442b44
Function name=JVM_DisableCompiler

at
and my server shut down as far as I know the driver olite40.jar is a JDBC-ODBC driver I think that this is the reason for the problem maybe if I use a driver type 4 I can work better but, is there other driver for Oracle Lite in windows 32??? type 4 could be a solution.

Fatal Internal Error: "image.cpp", line 13192 when trying to insert a cursor to graph

NOTE: This IS a duplicate post from the Breakpoint. Text slightly changed. The post in Breakpoint can be deleted. All comments should be placed in this thread.
I resolved the "Fatal Internal Error: "image.cpp", line 13192 when trying to insert a cursor to graph", but would like to share to find out if others have seen this and to determine whether this is a bug, or if it's time to redo my PC, or buy a new one..
I have an existing graphs (qt 6) which originally had 2 cursors. This occurred while trying to add the third cursor.
Up until attempting to add the last cursor, the program worked great, and I had been running tests for a while. However, I do recall seeing this problem when creating the original cursors, but not to this extent. Plus I don't remember the original error message from that time.
I needed to add one more cursor to the existing graphs. As soon as I add a new cursor and set it's properties, I get a nasty error message and without warning LV8.2 simply closes itself (well, the only warning was the error message. Tried it 3 times, same result.
Here are the steps:
Shut down the PC, went for a coffee, rebooted the PC. Opened the LV project, opened the VI. Immediately went to the graph properties to add the new cursor by doing the following steps:
Right click graph indicator icon on block diagram.
Select Properties.
Click on cursor tab.
Click on Add
Select Cursor 2 (3rd one, newly created)
Change color
Select cursor as a line
Remove checkmark for "show cursor"
Click OK
I need to do this to 3 other graphs, same steps. And as soon as I get to the step before clicking OK, I get the error message.
I managed to get an additional one done, by immediately saving after each step (yep going in & out of the properties). But I've had this problem before when creating the first two cursors.
Is it a bug? Anyone else seen this? Using LV8.2. And the message is right about LOOSING ALL unsaved work!!!!
Here are more observations:
Tried creating a new one on the second graph. As soon as I clicked on the color, it crashed!
See the error explanation below. It is really clear, now anyone can solve it    LOL!!... According to the error log, there's a bad image out there

I observed the title bar after making changes to the properties. I noticed that 3 out of 4 times, while changing the properties of the graphs to include the cursor, and saving after each & every step, that there were no stars appearing on the title bar to indicate "unsaved changes". Saving was also much slower than usual. I suspect, the program never got to placing the star before saving occurred. However, I am noting everything.
After creating the cursors, saving was and is normal, and the program runs well..   I have run tests without problems.
Does anyone have a clue at what causes this? Has anyone seen this before?
Thanks,
RayR

Hi Donovan,
I can't remember seeing this elsewhere. When I get a chance, I'll create a new (blank) vi with new graphs and will repeat the steps.
I will let you know if I see this in the new vi.
Thanks!

I have encountered the new error "Fatal internal error fpinit.cpp line 7398

I get the error message "Fatal internal error fpinit.cpp line 7398".
I use:
TestStand 2.0
LabView 7.1
Vision 7.1
uEye USb Camera
I've included into my TestStand programm some new steps that control the uEye USB Camera.
I use following steps (all steps written in LabView):
- Initialze Camera
- Wait
- Close Camera
- Wait
I have the settings "Load dynamically" in TestStand"
If I use also the setting "Unload after sequence executes" and start the sequence I get somtimes a LabView error after running the Step for the Camera initialization. LabView is sometimes immediatlly closed. This happen at leased after 10 turns/starts of the programm. If I use the loop functions "Loop on selected steps" it happen only sometimes at the first loop. The initialize Camera Step is every time pass, if TestStand try to run the next step I get a error.( Sometimes I get also the message ActiveX Server got lost)
I detected also that sometimes in this case a constant in a other vi is emty.
Normally I use the setting "Unload when sequence file is closed" then I have the problem only sometimes at the first turn.
If the initialize Camera step is succesfull I have no problem with further camera steps.
Regards
Alexander

Hi Alex,
I'd suggest to replace all ctl. with new ones.
Perhaps one of them is corrupt.
You will find a documentation about preferred execution system

Receive "Fatal Internal Error: Linker.cpp, line 1926 when run executable.

Hi, I use invoke node to call multiple subvi.vit, it work fine under .vi but when run under an executable I receive this error:
Fatal Internal Error: 'linker.cpp", line 1926
LabVIEW Version 7.0 You will lose any unsaved work. For more assistance in resolving this problem, please relaunch LabVIEW, or contact National Instruments.
Any suggestion will be very appreciated

Hi David,
What you are seeing is a known issue when calling LabVIEW 7.0 VITs from
an executable or DLL if the VITs include any Express VIs. It can happen if you
try to load
multiple instances of that template VI using VI Server.
There are a couple of workarounds for this issue:
Take
all the express VIs that are inside the template VI and turn them into
static subVIs. You can do this by right-clicking on the express VI and
selecting "Open Front Panel"; then save the express VI as a normal
subVI.
Build the entire application into a single executable, which will force all of the express VIs to get compiled as static subVIs.
Don't use the runtime engine at all and always run your application in development mode.
Let me know if the workarounds fix your issue, thanks.
Good luck!

Fatal Internal Error : "ThEvent.cpp", line 209

Hi,
Any help with the following AddRef()/Release() issue would be most appreciated:
I'm a software developer working on a COM (ActiveX) object for use by e.g. C# (test ok) and LabVIEW clients. The object supports events; however, when events are accessed with the "Register Event Callback" block, LabVIEW does not free the object when the VI is finished, and upon subsequently closing LabVIEW, I receive the following dialog:

I've attached a minimal COM server (that starts a thread when events are requested) that shows the issue. Steps to reproduce with LabVIEW 8.6 on Windows XP for x86 follow(stuff in parenthesis are comments):
(1) unzip HelloClass.zip to C:\ (4 files: hello.vi, callback.vi, HelloClass.dll, Hello.tlb)
(2) C:\>regsvr32 helloclass.dll (should get "DLLRegisterServer in helloclass.dll suceeded." dialog)
(3) C:\>hello.vi (start LabVIEW)
(4) Ctrl+R (run the VI. You should see "Command: test" in the String Indicator. At this point the last call into the server is AddRef() but should be Release())
(5) Alt+F4 (close the VI)
(6) Alt+F4 (close LabVIEW)
You may need to perform steps 3-6 up to ~10 times, because at this point one of 3 behaviors randomly occurs:
(A) Fatal Internal Error : "ThEvent.cpp", line 209
(B) Release() is finally called the same # of times as AddRef(), causing the destructor ~HelloClass to run (which kills the thread). This should instead happen after step 4 (which it does if you remove the "Reg Event Callback" block)
(C) Release() is called several times, but not enough to decrement the reference count to 0
Behavior A doesn't occur if the server doesn't start the thread. In source.zip, I've also attached the server's source code for your R&D team along with dbgMon, which is useful for looking at the _RPTF debug output. Thanks much for your patience and for looking at this.

Fatal Internal Error source/manager/thread.cpp line 3472 while starting LabVIEW

When I try to begin LabVIEW 7.1.1 on my mac OS X 10.4, I see the LV logo and then I get the pop-up window:
LabVIEW.app Alert
Fatal Internal Error: "source/manager/thread.cpp", line 3472

do anything, irrespective of what I click in that window.
The other window is called Controls.
The last message I see on the LabVIEW splash screen is Server: Exported VIs list ok.
The LV website says I need to make DLLs re-entrant, but I can't even begin LV to solve this problem.
Any suggestions?

Hi Enduro,
I would suggest creating a service request for this problem at ni.com/ask. The Applications Engineer will be interested in looking at the error log that is being created, so that we can determine if this problem has occurred before.

"Fatal internal error:"memory.cpp",line 593"

I need some help.
Can some please explain what i am doing wrong here. i have created a Dll from a LV 7.0 vi. The header file looks something like this:
typedef struct {
long dimSize;
double elt[1];
} TD2;
typedef TD2 **TD2Hdl;
typedef struct {
double f0;
double df;
TD2Hdl magnitude;
} TD1;
void __cdecl Spectrum(double freq, double amp, TD1 *Spec);
And i have the following code where i allocate memory and attempt to call 'Spectrum':-
TD1 *Power;
double frequency=10, amplitude=1;
Power = (TD1 *) malloc(sizeof(TD1));
(*Power).magnitude = (TD2**)malloc(sizeof(TD2));
*(*Power).magnitude = (TD2*)malloc(5000*sizeof(TD2));
(*Power->magnitude)->dimSize = 5000;
for (i=0; i<500;
i++) {
(*Power->magnitude)->elt[i] = 0;
Spectrum(frequency, amplitude, Power);
I keep getting Fatal internal error: "memory.cpp", line 593" when it tries to call Spectrum. I believe i have allocated memory correctly although i may be wrong. (I was getting 'exception' errors before). The VI i used to create the Dll contains a basic 'Function Generator' (sine wave) and a 'Power Spectrum'.
I have looked at the Knowledge base and dll examples that come with LV 7.0 and have tried setCINArray and NumericArrayResize but have not had any luck. It seems like the documentation is for LV 6.0 and 6.1.
Has anybody seen this or have any idea why i am getting this?
Thanks

It looks to me like you are constructing arrays to pass to LV using
malloc, instead of the labview.lib functions for creating or resizing LV
array handles.
You should refer to the manual on Calling External code for details on
the construction of an array.

Fatal Internal error: "oleautomgr.cpp", line 2832

Hi,
I have a program developped with LV 8.2.1.
Now I have import this application with LV 8.5; if I run the VIs in Labview it works; when I run my program (executable version) I got this error
"Fatal Internal error: "oleautomgr.cpp", line 2832"
I got the error after I open a Diadem connection.
Another information: first time I have import the program in LV 8.5 and I have save the prj, LV ask me to overwrite all the VIs of the "Diadem addons". (Diadem connectivity); so I have uncheck "read only" in Diadem.llb and I have save the Vi.
Someone can help me?
Thanx a lot

For the community's future reference, this issue was resolved by the customer calling in for support, at which time it was determined that a Mass Compile of the VIs was necessary to eliminate the error. The process to mass compile is described here.

Fatal Internal error: "oleautomgr.cpp", line 2832 when sending data by means of ActiveX methode

I have experienced error "Fatal Internal error: "oleautomgr.cpp", line 2832" during sending data to CAN card IXXAT iPCI-I XC16/PCI. LabVIEW communicates with that card by means of ActiveX methodes via "VCI Wrapper" which is COM object interface. Mass compiling of the project does not help. Card is initialized and configured propely. The driver card is working propely.
LabVIEW version is 8.5
The efect of that error is that labview completly shot down.
I appraciate any suggetions
thanks a lot

Hello,
Please try to reinstall the drivers for the CAN card, then make sure you close all references to the ActiveX control (at all levels) using the Automation Close primitive in LabVIEW.
Regards,
Emil
