What's the error called "segmentation fault (core dumped)"?

[vignesh2008]

Hi all,

I am using RHEL 6. When i use CAP3 software for the first time it successfully resulted. But second time when i used, it's showing "segmentation fault (core dumped)". Even after restarting and reinstalling it showing same error. When i google, i found it some memmory related problem. But no clear information. pls help me in this regard.

Thanks in advance.

An error in which a running program attempts to access memory not allocated to it and core dumps with a segmentation violation error.

Better if you can gdb if you have core.xxxx file of it.
if you have do following:

1. file core.xxxx to find out which binary program has created this core file.
2. gdb <program> core.xxxx
3. bt (by this at least you can find out where the core dump occured & search for this trace on google.)

If you reboot the system and re-run the software, does it still do it on the first try? If it succeeds on the first try, my guess is that it is trying to access a shared memory segment which is no longer available. Did you install the CAP3 software from repository, rpm file, vendor-provided installation tool, or build from source code?
