Title: errors: segmentation fault and others on certain jobs only Dear users I get errors as soon as I mpi caught error segmentation fault submit some jobs but not with others. The difference xorg caught signal 11 segmentation fault between the jobs may only be a change in number of atoms or

(Note that I http://lammps.sandia.gov/threads/msg42299.html reject some suggested additions on my belief that it is technical nonsense). I would appreciate it if you put "sig11" or something like that in the subject. You can also Email me about other subjects. The Sig11 FAQ QUESTION Signal 11, what does that mean? ANSWER Signal 11, or officially know as "segmentation fault", means that the program accessed a memory location that was not assigned. That's usually a bug in the program. So if you're writing http://tldp.org/FAQ/sig11/html/index.html your own program, that's the most likely cause. However, this FAQ will concentrate on the possibilities besides that. QUESTION My (kernel) compile crashes with gcc: Internal compiler error: program cc1 got fatal signal 11 What is wrong with the compiler? Which version of the compiler do I need? Is there something wrong with the kernel? ANSWER Most likely there is nothing wrong with your installation, your compiler or kernel. It very likely has something to do with your hardware. There are a variety of subsystems that can be wrong, and there is a variety of ways to fix it. Read on, and you'll find out more. There are two exceptions to this "rule". You could be running low on virtual memory, or you could be installing Red Hat 5.x, 6.x or 7.x. There is more about this near the end. QUESTION Ok it may not be the software, How do I know for sure? ANSWER First lets make sure it is the hardware that is causing your trouble. When the "make" stops, simply type "make" again. If it compiles a few more files before stopping, it must be hardware that is causing you troubles. If it immediately stops again (i.e. scans a few directories with "nothing to be done for xxxx" before bombing at exactly the same place), try dd if=/dev/HARD_DISK of=/dev/null bs=1024k count=MEGS Change HARD_DISK to "h
