Access violation (0xC0000005)

Hi
I am getting continuing problem with the crashing and Access violation (0xC0000005) at EIP=0x00962D22.
When the crash happens the vi is gettting corrupt and impossible to open next time, so I need to work of the back up.
I tried to recompile everything, change the type defs, update to LabVIEW 12, open on another PC, same thing. I can work for 10min save the work several times do different things, and at one point LV crashes with that error.
Any ideas what to do? It is really a show stopper for me.
The report dump below.
thanks

pawel,
I found your post here very interesting as I was having a VERY similar problem. The only notable difference I could find with my situation is I only seemed to encounter this problem on 64-bit systems, and only when my application was a deployed exe. However, I too was using a number of 3rd party .ocx and .dll utilities. But this stubborn Access Violation error was so sporadic (it might have triggered 5 seconds into execution, or 5 hours) it was near impossible to track exactly WHY it was happening.
Have you tried using the LabVIEW Desktop Trace Execution Toolkit yet? I used it to tap into my deployed executable on the target machine while monitoring all VI calls, memory adjustements, etc from my development machine. Although it wasn't a definitive sure-fire way to a solution, it did help me pin-point a pattern.
For about 80% of my crashes, I noticed the last applicable VI to execute (after filtering out a bunch of typical utility VI calls) was "Wait On ActiveX Event.vi". After a bit of digging, this VI was retired quite some time ago and has been upconverted from version to version since. It was written into a library that has been rock solid for years. Although it seemed to execute fine on my devlopment machine (as source code - not a built exe, 32 bit, 64 bit..whatever) and also functioned on all target 32-bit environments wrapped in an exe, it was actually the culprit to my Access Violation errors.
I know how frustrating it is to narrow something like this down. If you're still having issues and you haven't tried that Toolkit, I would suggest giving it a shot.
Good luck.

Crash: "Access violation (0xC0000005)"

Hello,
One of our programs has crashed (crash of LabVIEW Runtime).
The reason was an "Access violation (0xC0000005)" in the LabVIEW Runtime.
Because it was an Error of the LabVIEW Runtime, I can not log the Error. This Error occurs only very seldom > than every 3 weeks.
Attached is the error report and a Screenshot of the Error Window.
So I have no Idea how to locate the error.
1. What can cause this Kind Error?
2. How can I locate the error cause?
3. Can National Instrument isolate the error?
Thanks

These types of crashes are very conserning, and difficult to isolate (as you already have discovered). Here's what I've done in the past.
Memory monitoring. Built into Windows 7 and newer is the Performance Monitor. Not sure where it is I always click Start then type Performance Monitor. It lets you log data over time and I usually set it up to log my application (or LabVIEW.exe) and look at different memory. There are all kinds of memory from private, to public, and several variations in between. This it self doesn't fix anything but may help in predicting when it happens. If memory increases at some rate and it always dies around the same value it might help.
If you can predict, and reproduce the issue, try changing the code to see if the issue goes away, or happens faster. For me I made my logging routine run twice as fast. So for all data I log I log it twice. If the issue happens sooner it is likly something in the logging routine.
After that I did a binary approach where I would disable parts of the logging code until the issue when away. Turns out it was a bug in the TDMS logging routine that I could isolate and post to the forums. NI agreed and fixed it in an update, and also had a work around until the update went live.
Another thing I've tried is to upgrade to the latest everything and see if it behaves differently. I would make an image of the harddrive as a backup, then upgrade to the latest LabVIEW and drivers for everything. Then try again. In a few cases things were fixed by upgrading, and the cost of upgrade was less than the weeks it would take for me to track down issues that may or may not be my fault.
EDIT: Oh and giving the crash report to NI is a good place to start. Not sure what they can understand from it.

Access violation (0xC0000005) at EIP=0x012B60E6 within a dynamically called VI

Hi
I have been seeing Access violation (0xC0000005) at EIP=0x012B60E6 within a dynamically called VI.
The VI is called by reference and is strictly typed.
The VI controls a function generator, a robot and a microcontroller device.
All of the above are synchronised using functional globals.
If I let the code run the FG will operate so I know the top level dynamic VI has defiantly been called and successfully entered, however within that VI as other VI’s are called (there are many) LV crashes with access violation.
The VI's within the top level VI are using HiD communicatiuoins over USB with the peripheral instrumants.
The LV crashes are totally random and sometimes the code will operate until the end and close down successfully.
I can only seem to guarantee smooth operation if I set a breakpoint within the top level VI, then the entire system runs perfectly.
In fact it seems that even if I remove the breakpoint (after the first break) and close the VI the system will continue to run until close.
Has anyone any ideas? I have run out!

Hi MAC1,
I have been looking at your issue and wanted to ask if you are calling the VI's into Teststand, using the LabVIEW adapter?
If this is the case, it may be worth looking at another forum post regarding the issue.
LabVIEW Access Violations- Teststand
I am currently looking into what could have caused this access violation.
If you could provide any further information in regards to the top level VI or if you could post it on here, that would be really useful.

Access violation (0xC0000005) at EIP=0x0534BABC when launching Exe

Hi All,
I am facing "Access violation (0xC0000005) at EIP=0x0534BABC" issue when I tried to launch my exe. Earlier versions of the exe were running fine until I added Email notification features using .net SMTP APIs and built it again.
System,
Development and Deployment systems are different. I am able to run source code on both systems and Exe on Developement system. But exe is not working in Deployment system.
Exception,
I have attached the sanpshot of crash report pop-up and Log Report of the exception.
Please help!

Additional details,
When I tried "Run as administrator", I could see the exe icon on the task bar for few seconds then it disappears. It basically fails to launch, also I don't get any error message.
The Exe is created in development PC which runs 64 bit Window 7 and 32 bit LabVIEW. The deployment system has 32 bit Windows 7 and 32 bit LabVIEW. I hope it doesn't matter as far as my LabVIEW installations are 32 bit in both systems.

Access violation (0xC0000005) at EIP=0x00496F5C

I am getting the following error while I try to run a script from Teststand.
I am attaching the error log too . I am not sure what the problem is .

Hi,
Then you need to debug the code for GB2_COM.exe.
If the code is not available for you to debug then few things which you can try :
Add steps to do manual flushing at different instances.
Add wait steps before you call this GBCOM steps (probably some synchronisation problem) or try running with different tracing speeds.
Hope this helps.

How to resolve and debug access violation Error.

Hello
I'm stucked with an access violation error which forces my exe build to shut down. I tried also from development environment but its the same there. The error happens after 5-60minutes.
I played around with disabling a part of the program where it was possible and I think I'm now able to accuse the vi "gastimer.vi". But since this vi leads through the measurement procedure, there are some commands outgoing which I was not able to map one to one.
My question is: what can cause such access violation errors? I have no dll calls, no third party library, actually the hardware communication is done serial by COM ports. The architecture principle is something adapted from producer consumer loop, except that i have often more than one consumer, so I called them like controller loop - multiple task. The communication within this loops (tasks) are done by queue cluster with an enumerator and variant.
The indicted vi "gastimer.vi" was transfered from an older and more simply architecture. This vi works with sequence structure and a lot of local variables.
Since I'm testing sensor on their response to gas concentration I have 10 comports to which I'm listening in parallel.
What styles or archtiecture are prone to access violations? Where can they happened? where should I look more carefully in the code?
How can I use the desktop execution trace toolkit to get more information about the cause of the access violation?
Attached are two different lvlog but I guess with the same error source. In the second lvlog are two vi's named. What have they to do with the access violation error? What kind of information can i get from these lvlog files?
Last attachement shows a runtime fatal error which happens quite a bit frequently in the recent time when working with this project. Might there be a connection, propably a crashed vi, typedef or whatever?
Thanks for any help

Access Violation in CallStaticVoidMethod() using JNI

Hey all,
I have a C++ app which I successfully used about a year ago to put up a Java dialog from within QuarkXPress, which has a C/C++ API. I got it out and rebuilt it and ran it, and I am now getting an Access Violation (0xC0000005) exception in JVM.dll somewhere. I am getting the exception in the CallStaticVoidMethod() call. Here is the relevant snippet from the method I am using: if anyone can spot anything obviously amiss, I would appreciate knowing about it! (This snippet borrows heavily from the "invoke.c" example program in the JNI tutorial.)
JavaVM *jvm;
jint res;
jclass cls;
jmethodID mid;
jthrowable except = NULL;
JavaVMInitArgs vm_args;
JavaVMOption options[2];
char newcpath[512];
char newlibpath[512];
sprintf (newcpath, "-Djava.class.path=.;C:\\Program Files\\QuarkXpress 4.0\\XTENSION");
sprintf (newlibpath, "-Djava.library.path=.;C:\\Program Files\\QuarkXpress 4.0\\XTENSION");
options[0].optionString = newcpath;
options[1].optionString = newlibpath;
vm_args.version = 0x00010002;
vm_args.options = options;
vm_args.nOptions = 2;
vm_args.ignoreUnrecognized = JNI_TRUE;
/* Create the Java VM */
res = JNI_CreateJavaVM(&jvm, (void**)&env, &vm_args);
if (res == JNI_EEXIST)
    JavaVM *jvms[1];
    jsize nVMs;
    res = JNI_GetCreatedJavaVMs(jvms, 1, &nVMs);
    jvm = jvms[0];
    jvm->AttachCurrentThread((void**)&env, NULL);
else if (res < 0)
    return UNKNOWN_ERROR;
cls = env->FindClass(g_javaName);
if (cls == 0)
    checkException();
    destroy(jvm);
    return MISSING_CLASS;
mid = env->GetStaticMethodID(cls, "main", "([Ljava/lang/String;)V");
if (mid == 0)
    destroy(jvm);
    return MISSING_METHOD;
env->CallStaticVoidMethod(cls, mid);

Hi ,
The method id that you get is for the public static void main(String args[]) of a class.
mid = env->GetStaticMethodID(cls, "main", "([Ljava/lang/String;)V"); if (mid == 0)
destroy(jvm);
return MISSING_METHOD;
env->CallStaticVoidMethod(cls, mid);
Change the above line to
jstring jStringArgs[];
env->CallStaticVoidMethod(cls, mid, jStringArgs);
You need to pass an argument i.e. an array of jstring .
It is immaterial that they possess valid value or not .

UIManager ClassPath ignored? (access violation)

Appologies if this is a second post, but I do not believe my previous post worked. I do not see it in the list of topics...
I've encountered a serious problem: I can not use any 3rd party look and feel
implementations inside the Java Web Start secure sandbox. More specifically,
they work unless you use the FileOpenService or FileSaveService, which bring
up a JChooser with UI components that are in the wrong ClassLoader and cause
access violation exceptions.
Some code I have tried to (unsuccessfully) work around this problem:
// Attempt #1
ClassLoader jwsClassLoader = this.getClass().getClassLoader();
UIManager.put("ClassLoader", jwsClassLoader);
SlafLookAndFeel slaf = new SlafLookAndFeel("com.memoire.slaf.SlafLookAndFeel"); UIManager.setLookAndFeel(slaf);
This brings up the SLAF look and feel for everything but the FileOpenService.
Exception pasted below.
// Attempt #2
// After executing the above code, I also run this:
Hashtable tb = UIManager.getDefaults();
tb.put("ClassLoader", jwsClassLoader);
Enumeration e = tb.keys();
while (e.hasMoreElements()) {
Object obj = e.nextElement();
if (! (obj instanceof String))
continue;
String k = (String)obj;
if (k.endsWith("UI")) {
Class uic;
try {
uic = jwsClassLoader.loadClass(tb.get(k).toString());
} catch(Exception ex) {
// classnotfound...
continue;
tb.put(uic.getName(), uic);
Again, this does not help.
// Attempt #3
In Sun bug:4155617 the username 'awiner' posted a message that contained
some code to register your own ClassInstantiator (implements UIDefaults.LazyValue)
I would like to try this, but I do not know how to use the code presented.
I think it needs to be integrated within the Look and Feel code?

LabVIEW Access Violation Crashes

We've been seeing numerous LabVIEW crashes when calling VIs through the LabVIEW adapter in TestStand. I've searched the knowledge base and discussion forums without success and figured I would post here before opening a help request.
The actual error we see is:
Exception: Access violation (0xC0000005) at EIP=0x012B60E6 Version: 11.0.1f1
We see these crashes several times a day, but while calling no specific VI. They happen mostly on 2 PCs that are running Windows 7 - 64 bit, but I think we've seen them in the past on PCs running the 32 bit version of Windows 7. Here is the data related to those 2 problematic PCs.
OS: Windows 7 Professional SP1 64 bit
LabVIEW: 2011 SP1 (11.0.1f1) 32 bit
TestStand: 2010 SP1 (4.5.1.134) 32 bit
PC: Dell Optiplex 790 with Intel Core i5
Other significant information.
We see these crashes when we're running the batch model in TestStand with multiple threads open. Some VIs are reentrant, and some are not.
The 2 PCs that run the batch model (with multiple threads) have the 64 bit version of Win 7 Pro, and crash most often.
The 3 PCs that run the sequential model or the batch model with a single thread have the 32 bit version of Win 7 Pro and rarely if ever have crashed.
Not sure if it's related to the OS version or the multi-thread usage and switching the PCs/OS versions to isolate that isn't easy.
Has anyone else seen similar issues? Does Windows 7 Pro 64 bit work reliably with LabVIEW 2011 32 bit?
Any information would be appreciated.

Hi Amezam, thanks for your reply.
We appear to be having different access violations each time (or they are one of a large group of them, we cannot tell).
The crashes appear to be at random, we cannot connect the crashes to any specific sequences of events and we cannot reprocude the crash consistently on the same piece of code! One pattern I have noticed, however, is that the violations appear to coincide with a peak in program activity - very frequent indicator updates for instance*.
I am unable to disable antivirus protection at will, but I will raise it with our IT Support to see if we can try that.
I believe that we are intearacting with external code - 3rd party device drivers which include packed libraries. I have no control over these and, furthermore, if I were to remove them the code would not be able to function at all. However, if you think it is a good idea I can attempt to create a separate piece of code which calls the same driver function very rapidly to see if that is the problem.
As for error handling - those nodes which use them only return error codes from the base 3rd party libraries, which according to the documentation only return custom error codes (these are not related to the error/crash that we are seeing). If you think it's still possible that they will return an Access Violaton error and crash, I will link them up.**
* - sidenote: I implemented a method of reducing the number of updates to a graph indicator (from several times a second to several times a minute) - this has reduced the problem significantly.
** sidenote 2: Some of the nodes which return custom errors are linked properly, and they are not returning errors; these ones are the most likely to return errors since they are called extremely frequently. I am not seeing anything except the documented custom error codes from them.

LabVIEW Access Violation Crashes from TestStand

We've been seeing numerous LabVIEW crashes when calling VIs through the LabVIEW adapter in TestStand. I've searched the knowledge base and discussion forums without success and figured I would post here before opening a help request.

Any information would be appreciated.

I just had the same error in a LVOOP Project. First I got a crash (something with out of memory). The I got subsequent Access Violations. Could trace it down to one VI that:
a) had been working just fine before
b) wasn't changed after test mentioned in a) but got (even just running on its own) subsequent access violations every time I ran it
c) VI used a class konstant, property node (to set 2 class attributes); Inputs were a string and an integer and an error cluster; outputs: one instance of the class (initialized with string an integer) and the error cluster
d) Problem could be solved by deleting the class constant used in the VI and put the same in again (an just rewired the thing); I assume this caused a recompile that solved the prob
Maybe this helps narrowing the general problem down.
P.S: I dont have a still non working version of that VI, since I was happy to have solved this and just saved the VI before thinking about making a copy.

0xC0000005 Access Violation in cvirte.dll (SetWindowsErrorMode?)

Hello,
We will occasionally see a crash with our CVI LabWindows based 2010 SP1 application, a 0xC0000005 Access Violation exception thrown from within cvirte.dll. The app is working primarily from a spawned thread when the crash occurs. I've been able to get it consistently on a Win7 x64 VirtualBox VM and have some data that may be of use if someone there would like to investigate.
When I track down the location of the instruction pointer (work below) it seems to be in the "SetWindowsErrorMode()" function (at least going by the exports in DependencyWalker):
1. The IP is 0x687B5F1C at the time of the crash.
2. The base module address for cvirte.dll is 0x68420000, so the IP is 0x395F1C bytes into the DLL.
3. Using DependencyWalker on cvirte.dll and sorting by entry point indicates that the IP is inside of "SetWindowsErrorMode()" at 0x003938D0, which comes before "MinimizeAllWindows()" at 0x003984B0.
Coincidentally, this crash happens in CVI 2013 F1 as well, the offset within "SetWindowsErrorMode()" is a bit different (0x264C past entry in 2010 SP1, 0x2D0C past entry in 2013), but locally the code looks the same in my VS2010 disassembler:
CVI2010 SP1
*Address *Code Bytes *Instruction

I have dump files (mini, or mini+heap) for both builds if it would help.
This bug seems semi-similar to the thread "Is InstallPopup not threadsafe?":
http://forums.ni.com/t5/LabWindows-CVI/Is-InstallPopup-not-threadsafe/m-p/716822/highlight/true#M359...
Just for posterity, I'll add the data for the 2013 build. IP is 0x687CA2CC, DLL Module address is 0x68420000-0x68A28000, so offset is 0x3AA2CC. "SetWindowsErrorMode()" enters at 0x003A75C0 in this dll, and "MinimizeAllWindows()" is at 0x003ACB20.

Hi Kelsey,
Apologies for the long response time, I didn't receive a notification for your post.
> What does your application do?
Our application is used in this context to setup and run our vehicle simulations on a Windows based PC.
> And, what is it doing at the time of the crash?
At the time of the crash a simulation is being launched and run on another thread from the default thread pool like this:
CmtScheduleThreadPoolFunctionAdv (DEFAULT_THREAD_POOL_HANDLE,
sRun,
NULL,
THREAD_PRIORITY_NORMAL,
NULL,
EVENT_TP_THREAD_FUNCTION_END,
NULL,
RUN_IN_SCHEDULED_THREAD,
&sThreadFuncId);
That spawned thread will load a simulation DLL, read some data as input, run the simulation, output the results, then close the DLL.
As I noted earlier, I couldn't get it to happen on my desktop, but I could get it on the VM when I used a very slow storage device for the I/O of the simulation (a slow thumb drive attached to the VM). My boss was seeing the issue on his virtualized PC on his Mac, typically only when he used a slower storage device as well (network storage for example).
> When you reproduce this issue in 2010 and 2013 f1, are you using the same computer or using different machines?
Both of these crash dumps were produced on the virtual machine as described.
> For each dump file, which version of LabWindows/CVI were you running? You can find the version number by selecting Help»About LabWindows/CVI within LabWindows/CVI. Which version of cvirte.dll do you have? This will be located in System32 and/or SysWOW64.
The development environment installed was CVI 2010 SP1. So the 2010 dump was just using the runtimes bundled with that installation. I then installed the 2013 F1 runtimes to see if the same issue persisted.
It's possible I did a clean install with the 2013 F1 dev environment, I will double check this tomorrow when I have access to the virtual machine.
Thanks for looking into this--

InitCVIRTE generates error message "Unhandled exception in "MyApp.exe": 0xC0000005: Access violation reading location 0x00000000."

Hi,
I have converted a LabWindows CVI project to Visual Studio 2005. When I start the application i debug mode I get the message "Unhandled exception at 0x685662ba in EE352-500V.exe: 0xC0000005: Access violation reading location 0x00000000."
It comes when the application calls: InitCVIRTE in this context:
int __stdcall WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpszCmdLine, int nCmdShow)
// Initialize LabWindows/CVI run-time library
if (InitCVIRTE (hInstance, 0, 0) == 0)
return -1; /* out of memory */
The debugger indicates that value of hInstance is 0x00400000 {unused=9460301}
Can someone give me a solution to this problem. I have done some search on the Web without success.
Thanks!

I think that exception might be coming from the data execution prevention service that is part of Win XP SP2. The OS thinks that you're somehow trying to execute in the data segment and kills the process. It's intended to catch worms and viruses.
You can turn this service off for non-Microsoft programs using the control panel.
Many pointer handling errors now report as this exception instead of as a memory violation exception. That looks like a null pointer derefence to me.

0xc0000005 access violation running app from mapped drive but no problem from UNC or local

I have an application (.exe - 32 bit) that is giving the access violation error when run from a mapped (net use) drive on a shared folder.   NO error if I run it using the FULL UNC path name and NO error if I copy it to my local drive and run it.
The error is below.   I have run scans for virus and malware, etc. and come up with nothing. I have run diagnostics on my memory and nothing is wrong with the hardware. Also, if I create a new user profile, the app will run fine under
that profile - initially.   The problem seems to come up after I install something new.  I know the new software is not infected (VS 2013) and the software installed before the new profile test was not the same software.
I didn't give all the info below because it's legacy software few would know about and I do NOT have the source code.   It is 32 bit and has worked fine for 15 years or more - without this problem.    Thanks in advance for any help
you can provide.

Hi Johnny，
We wonder if you get this error on all PCs or only on your Windows 7 PCs.
If your application happens to hit a page of memory that is not present, a standard page fault will trigger, telling Windows it needs to fill that page. If the network happens to be down at that moment, Windows will be unable to satisfy the page-fault. So
Windows throws an EXCEPTION_IN_PAGE_ERROR (0xC0000005). Since you mentioned that it works under new user profile initially and already tested your memory, the most typical causes for the ‘0xC0000005: Access Violation’ error are: corrupt registry, malware,
updated software/device driver.
Check your issue with malware, VS 2013 and firewall closed under new account.
If this issue happened recently, you could simply restore your system to earlier point then check your issue.
Check your issue under clean boot and safe mode with network (using new account)

0xC0000005 Access Violation

Hi all,
I realize there are quite a few threads with a similar Crash report and I believe I have read them all, but I hope someone can help me out here.
In this particulair program I customized some GUI stuff, mainly gauges and a couple of static bitmaps on the background. This means the 'backbone' runs on various other projects. Still for some reason it keeps crashing with a 0xC0000005 Access Violation. The Exception is at EIP 0x07E504A3. The program runs on a server computer to which 4 tablets (that run Windows 8.1) connect using an application reference. This setup proved very stable in various projects and hardly ever changes.
The problem is that the server pc (running Windows 7 pro, admin user) crashes about once every day with this report. My customer has swapped the PC for a brand new one, but it still crashes every day.
I have ran the application over here on a Windows 7 machine, with the same setup, but it seems to run just fine.
Any help would be greatly appreciated.
Chris
