LabVIEW caught fatal signal

I am running the LabVIEW HTTP-server on a Linux server. When the traffic is to high LabVIEW crashes and I get the following error:
LabVIEW caught fatal signal
6.0.2Received SIGSEGV
Reason: address not mapped to object
Attempt to reference address: 0x0
See LabVIEW_Failure_Log.txt for more information.
The LabVIEW_Failure_Log.txt looks like this:
#Date: Mon, Feb 18, 2002 02:48:30 PM

I am getting a similar error with LV70 Linux when
trying to start it in a WRQ window. Is there
an answer to the question?

LabVIEW caught fatal signal - Segmentation fault

Hi,
I've just obtained the Linux version of LabVIEW 7.0 from my University for academic use on my home PC, and I am having some difficulty getting the program to run. I've installed all of the "labview70-*.rpm" files into "/opt" using the "bin/INSTALL.norpm" from the CD (I am running Gentoo and don't have RPM support).
When I try to run the program (cd /opt/lv70, ./labview), I get the splash screen, which says "Init temp resources file" in the bottom right corner. This stays on screen for about a minute, during which time, my RAM usage gradually goes very high, followed by my SWAP usage when the available RAM runs out (256MB RAM, 500MB SWAP). This happens regardless of whether I'm logged in as a normal user or as r
oot.
The splash screen eventually disappears and the following message is printed at the terminal:
LabVIEW caught fatal signal
7.0 - Received SIGSEGV
Reason: address not mapped to object
Attempt to reference address: 0x70126d74
Segmentation fault
I have checked the FAQs and knowledge base but can't seem to find anything that sounds similar to what is happening on my machine.
My system is as follows:
Athlon 1800+ XP
256MB RAM
Gentoo Linux 2.4.22-r2
500MB SWAP partition
24GB free space on hard disk
Cheers,
Martin

Hey Martin,
This is a new one for me. Try replaying your INSTALL and bin/INSTALL.norpm files with the one's that I've attached. They work well on my Debian machine (no rpm). That way you can run "./INSTALL" instead of INSTALL.norpm (which was only meant to be a helper app, not a primary method for installation.)
As you probably know, reproducing a gentoo issue may be difficult because of the extreme customization. Is there anything uncommon that you might be doing? (using a locale other than C or POSIX, using a different threading library, etc.)

LabVIEW caught fatal signal, reason unknown

hi, I have installed Labview 7 on Fedora Core 5 and it rans well untill yesterday, when I start labview, after the welcome picture, nothing more.
So I typed the command ``labview" at the shell prompt. Then the shell response me:
[root@silver ~]# labview
LabVIEW caught fatal signal
7.0 - Received SIGSEGV
Reason: unknown

I am very puzzled, coz it worked well before yesterday. All what I do is installed the ATI Radeon driver program onto my computer.
Can any one help me?

This problem is reproductible, my application crashs every time after
40-48h running, .
-- It looks like you have the 7.1.1 maintenance release installed and
I am assuming that you have seen this <a
href="http://digital.ni.com/public.nsf/websearch/A2D53C8E0D88380B86256EBD00..."
target="_blank">KnowledgeBase</a> about similar installation
errors.  However, this KnowledgeBase also offers some steps for a
workaround.. have you tried these?--
Yes, I tried it. We have this problem at beginning and we correct it
but it is not the same one because without this realease you can't
launch Labview. And my application run without problem during 40-48h.
Have you heard about any function not supported by Labview under Linux
environment ? It may help me to go on debugging.

What about booting into single-user mode from network or cdrom, mount your root filesystem and then add the patch using patchadd -R?

LabVIEW blocking QT signals?

I have a LabVIEW 8.6 program that is using a DLL written in QT; the DLL listens to a TCP port for incoming messages and updates some internal data. My LabVIEW program calls into the DLL occasionally to read the internal data. The DLL works perfectly (i.e., receives data from the TCP port) with another QT program. However, it does not work at all with my LabVIEW program.
I've attached a debugger to the DLL and can see calls from LabVIEW going into it -- my function for getting the internal data is being called and I can step through it. The code that gets the data from the TCP is never called though; it looks like the signal for incoming data on the TCP port is never triggered.
I know this sounds like a QT issue but the DLL works perfectly with another QT program. Unfortunately, it fails miserably with LabVIEW.
One theory:
   - The event loop is not running when LabVIEW calls the DLL
- In the QT DLL's run() function, I call socket->waitForDisconnected(). Perhaps the DLL is not processing incoming events because the event loop is not running? If I call exec() to start the event loop, LabVIEW crashes (LabVIEW 8.6 Development System has encountered a problem and needs to close."):
   AppName: labview.exe    AppVer: 8.6.0.4001    ModName: qtcored4.dll
   ModVer: 4.5.1.0    Offset: 001af21a
- Perhaps when I call the DLL from another QT program, that program's event loop is allowing for the TCP signal to be seen by the DLL. Unfortunately, kicking off the event loop in the DLL takes down LabVIEW.
Any thoughts on how to keep signals running in the DLL when LabVIEW is the calling program?
(Cross-posted on http://stackoverflow.com/questions/1267804/labview-blocking-qt-signals)

Hi,
calling a dll in LabVIEW can be tricky. Qt is based on C++ and LabVIEW do not like C++. A dll written in C++ needs to be redefined in how calling conventions must be. There is some App. notes you should read. Please search for them here or at lavag.org.

FPGA CRIO LabView - Why No Signal or Low signal?

I'm programming LabView 8.2/RealTime 8.2 on a CRIO-9002 equipt with a 9102 chassis. I have a some 4-20mA modules, +-10v modules and last but MOST IMPORTANTLY a 9233 +-5v module.
I've programmed the FPGA and realtime and have been able to acquire and scale appropriatly for all modules except the 9233. The 9233 is hooked up to a VibraMetrics 7002 accerlometer. (http://www.vibrametrics.com/downloads/specsheets/Model%207002.pdf)
When run and an acceleration is applied I only see very low voltage on my display. Why is my 9233 is being unresponsive?
Test run at 3.5 Gvms of acceleration: (please excuse the mess)
Once again, the power spectrum should not be showing levels so low.
Thanks for your help in advance,
Craig

Have you checked the signal level from the accelerometer with any other measurement devices to verify that the 9233 is measuring incorrectly? Is the voltage/current excitation for the accelerometer correct? I am assuming you are using the binary to nominal VI for converting the binary data to the real voltage. Make sure you are using the correct module type for the conversion.
I am attempting to use the binary to nominal VI on the values I see on your front panel, but things are not adding up. I used the 4th LSB Weight and Offset (656368 and -6548405)and the 4th 9233 unscaled Binary value (-7261) and converted it with the Binary to Nominal VI for the 9233 and got 0.00178252 for a nominal value while your VI appears to display 0.0067847. I'm not sure what you are doing different than me.
The low valued power spectrum makes sense because the analog input values are low. If we fix the analog input issue, the spectrum should take care of itself.
Without seeing your code or setup, these suggestions are obviously hypothetical. Your screenshots show the FPGA code ok, but we have no idea how you are handling data on the host side. In the future I would avoid embedding giant screen shots in your post, attachments are just fine. Embedded screen shots are more effective if they only contain a small snippet of code.

How to power a motor using labview DAQ output signal

The power from labview is not enough to move a decent-sized motor (works with tiny one). Is there any electrical component/device that I can use to sort of increase it (something in between output from labview and the motor)?
Thanks

LabView is a software and does not supply any physical signals. To generate physical signals you need an interface board, NI has plenty of them which can be controlled via LabView. Anyhow, as you mentioned, digital i/o interfaces can handle currents in the mA range only. I think the best way to control motors via LabView and an interface board is using an additional relay driver board. Since relay contacts only switch power and do not supply any power you will need an external power supply matching the voltage and current specs of the motor.

Labview driver for signal generator can not find DLL

The labview driver "age82xx.zip" I downloaded from NI website can not find DLL "age82xx_32.dll". There is no this dll file in the zip file. Please help me. The labview version is 7.0. The instrument is Agilent E8254A. Thanks!

On the download page, there is a link under "Require Third-Party Installation(s)". This is explained at the top of NI's page. Clicking on the link will take you to Agilent's web site where you will have to select the 'Signal Generators' link to get the E82xxA driver.

How LabVIEW get interrupt signal from microcontroller

Hello,
I try to write a LabVIEW program to test PC Oscilloscope using microcontroller and parallel port.
The program will triger the microcontroller and wait for the interrupt signal from the microcontroller.
Then read the data and show the display.
I defined my ECP port as bi-directional and IRQ enable.
The problem I faced in here is how to get interrupt service in LabVIEW 5.1 without DAQ board.
My computer's IRQ is 07 and I would like to control interrupt service by using parallel port.
Thanks in advanced.
Best Regards,
HMU

Hi,
I was very interested looking for possible answers to your question - no feedback from other people - o.k.
I think, that I have some experience with LabVIEW and
the use of printerport on different operating systems (Win9x,WinNT,W2k). But I would solve your problem with
polling of that "filtered" bit on printerport. If some- body has a better idea - let me know. If you have questions about interfacing @ printerport - please write to: [email protected]

AT300SE-101. Android Fatal signal 11 (SIGSEGV) in WebViewCoreThre

Using a Toshiba AT300SE-101 v4.1.1 (with others tablets it works ok), and a simple app, the app dies with a [error|http://pastebin.com/DUG1YVJq].
My code
[AndroidManifest.xml|http://pastebin.com/siAiMSXa]
[MainActivity.java|http://pastebin.com/RqnMnME9]
Without settings.setUseWideViewPort(true); or settings.setLoadWithOverviewMode(true); it works ok.
I think it's a hardware problem
Anyone know something?
Thanks!

Hi Joni
I doubt that someone here in the forum would be able to help you.
Your question is related to Android app coding and in my opinion you should check some android app developer places like for example: +xda-developers.com+

"Using a CIN to Create an Array of Strings in LabVIEW" example crashes LV on Linux

Tried to utilize this NI example: "Using a CIN to Create an Array of Strings in LabVIEW" (http://sine.ni.com/apps/we/niepd_web_display.display_epd4?p_guid=B4B282BE7EF907C8E034080020E74861&p_node=&p_source=External)
Compiles OK with the makefile made by the LV's lvmkmf utility. Nevertheless when I try to run the VI (with the code loaded into the CIN, of course), LabVIEW 7.1.1 on a SUSE 9.3 Linux machine crashes:
LabVIEW caught fatal signal
7.1.1 - Received SIGSEGV
Reason: address not mapped to object
Attempt to reference address: 0x0
Segmentation fault
Any ideas? Did anybody try this on a Windows machine?

This code is badly broken. In addition to resizing the actual handle to hold the number of string handles you also would need to create the string handles itself before attempting to write into them. NumericArrayResize is the fucntion to use as it will either resize an existing handle (if any) or create a new one if the value is uninitialized (NULL).
/* resize strarr to hold handles to NUMSTRINGS strings */
err = SetCINArraySize((UHandle)strarr, 0, NUMSTRINGS);
if (err)
goto out;
/* perform this loop once for each element */
/* of array of strings being created */
for (i = 0; i < NUMSTRINGS;) {
LStrHandle handle = (*strarr)->arg1[i];
/* determine length of string that will be element of strarr */
strsize = StrLen(str[i]);
err = NumericArrayResize(uB, 1, &handle, strsize);
if (err)
goto out;
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
/* moves strsize bytes from the address pointed to */
/* by str[i] to the address pointed to by the data pointer in the handle */
MoveBlock(str[i], LStrBuf(*handle), strsize);
/* manually set size of string pointed to by *strarr */
(*((*strarr)->arg1[i]))->cnt = strsize;
/* manually set dimSize of strarr */
(*strarr)->dimSize = ++i;
return noErr;
out:
return err;

Programming a c application which is calling a *.so built by LabVIEW.

Hello all,
This question probably has been asked, but I can't find the answer. So here's my question:
I have built a LabVIEW *.so in Linux and I want to call it from a "c" application. The LabVIEW *.so is returning a cluster of strings and I want to know how to call it from my c application (memory allocation?).
Here's the *.so source code, the function is named "testvi":
Here's my c application source code:
#include <stdio.h>
#include <string.h>
#include "testclusterofstrings.h"
int main()
Cluster_Of_Strings clusterofstrings;
Testvi(&clusterofstrings);
printf("-------------\n");
printf("String_A: %s", (*clusterofstrings.String_A)->str);
printf("-------------\n");
return 0;
I'm getting the following output when calling my application:
LabVIEW caught fatal signal
13.0 - Received SIGSEGV
Reason: address not mapped to object
Attempt to reference address: 0x0x19f5c381
Segmentation fault (core dumped)
So, what is the proper way to do this?
Thanks,
Michel

If its a labview-built dll and you're passing parameters by ref, I'm not too surprised you have to initialize it (although I would expect labview to be friendly enough to allocate the data structures for you). Maybe if you passed it a null pointer instead it would work? From your original post, maybe try this:
int main() {
Cluster_Of_Strings * clusterofstrings = NULL;
Testvi(clusterofstrings);
For some reason I remember reading that labview will interpret the null as a sign that it needs to allocate the structure, but I could be totally insane on that point.
If that doesn't work, then yes you'll have to allocate all the handles as appropriate. From <labview>\cintools\extcode.h you can see that a string is defined as follows:
typedef struct {
int32 cnt; /* number of bytes that follow */
uChar str[1]; /* cnt bytes */
} LStr, *LStrPtr, **LStrHandle;
Since you have size-0 arrays I think you really just need to call DSNewHClr(sizeof(int32)) which will allocate a handle with all 0s, and 0 is what you want. Final result would be...
int main()
Cluster_Of_Strings MeasInfo;
MeasInfo.String_A = (LStrHandle)DSNewHClr(sizeof(int32));
MeasInfo.String_B = (LStrHandle)DSNewHClr(sizeof(int32));
Testvi(&MeasInfo);
Oh, and for the string functions, make sure you look at the built-in functions first before you make your own.
Actually, the whole thing is both a little easier and more complicated at the same time. LabVIEW is fully managed with its data types but you have to follow that management contract when you interface to LabVIEW code from C.
First, the first attempt with allocating a string handle with sizeof(int32) + sizeof(uChar) bytes without initializing the length element is wrong. That length element could contain any value and cause LabVIEW to wrongly assume that the handle is already big enough to fill in its data and not do anything and then writing over the end of the allocated buffer.
Also initialisation of the structure with NULL is not going to work. This cluster has to be provided by the caller as it is a fixed size data area passed in as a pointer. However initialisation of the string handles inside the cluster with NULL should work fine, since LabVIEW considers NULL handles as the canonical zero length handle.
However after you have called the LabVIEW DLL function you are the owner of any memory that was allocated by that function and returned to you, just as you would be if you had allocated those handles yourself before the call. So proper etiquete is to also deallocate it and this is not optional but a requirement or you create memory leaks. It doesn't get noticed here since your test program terminates anyhow right after but it will bite you badly in a bigger application if you forget this.
The code could then look something like this:
int main()
Cluster_Of_Strings MeasInfo;
MeasInfo.String_A = NULL;
MeasInfo.String_B = NULL;
Testvi(&MeasInfo);
printf("-------------\n");
printf("String_A: %s\n", LV_str_to_C_str(MeasInfo.String_A));
printf("String_B: %s\n", LV_str_to_C_str(MeasInfo.String_B));
printf("size %d", (sizeof(int32) + sizeof(uChar)));
printf("-------------\n");
if (MeasInfo.String_A)
DSDisposeHandle(MeasInfo.String_A);
if (MeasInfo.String_B)
DSDisposeHandle(MeasInfo.String_B);
return 0;
// Returns the pointer to the string buffer in a LabVIEW string handle that has been made
// sure to be zero terminated.
char *LV_str_to_C_str(LStrHandle lv_str)
if (lv_str && !NumericArrayResize(uB, 1, (UHandle*)&lv_str, LStrLen(*lv_str) + 1))
LStrBuf(*lv_str)[LStrLen(*lv_str)] = 0;
return LStrBuf(*lv_str);
return NULL;
