LabVIEW caught fatal signal

[elen]

I run my application on runtime, and it return the following error.

I know there is a similar error (which is fully documented) but mine
occured only after 48h of runtime (without significant error). Do you
have any idea ?

Tanks for your help.

Hi elen,

Is this problem reproducible, or has it only happened that one time?  Of course, with a 48 hour test time I can understand if you don't know.  It looks like you have the 7.1.1 maintenance release installed and I am assuming that you have seen this KnowledgeBase about similar installation errors.  However, this KnowledgeBase also offers some steps for a workaround.. have you tried these?

This problem is reproductible, my application crashs every time after
40-48h running, .

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.

Hi elen,

I've looked through our databases, but I haven't found anything that would cause a LabVIEW program to crash after 40 hours.  I wouldn't be an unsupported function because it would crash immediately.  The SIGSEGV error indicates that there was an invalid memory reference.  Are you calling any DLLs that could potentially reference invalid memory?  Perhaps something with an array that gets larger and larger?  Although testing for a bug that only occurs after such a long period of time is tedious, I might try removing some functionality from the project and testing it to see if you can pinpoint where the code is going wrong.
