the 4th column means “If the region was mapped from a file, this is the major and minor device number (in hex) where the file lives”
In the above, ca:01 I can find through /proc/devices /dev
Question is that what does "00：16" 00 means which major device?

Aborted
How can I fix that error? Thanks...

You are freeing memory that you didn't allocate. The first such example is residentData.
You assign it in main to be argv[1] and latter call delete[] on it, although you did not allocate it. (Technically, you did allocate it. you just replaced it with argv[1] later).
As suggested by #Basile Starynkevitch, you probably want to run your code under valgrind. It'll pinpoint many memory errors.

You don't get the error at compile time, but at run time.
I suggest compiling with g++ -Wall -g (and improve your code till no warnings are obtained) then debugging the memory leaks with valgrind and of course the usual gdb debugger.

openMPI bug using mpirun, i get :

Since 2hours, my openMPI installation is out of order... i don't get why!
I got 3 serveur (call clusterX) that was running like a charm until today.
The thing i try was to lanch my MPI job using Nohup command in order to logout my SSH session and let my process run over night.
It worked.
But now, i can't run any mpi jobs, i get all the time this message :

if someone as a idea to what i have to do?
I am running all the nodes under Ubuntu 10.04 64Bits
Thank's in advance.

Finally i found out that there is no problem ^^
just have to make a new folder and lanch my app again, and it worked...
don't know exactly what i have modify into this folder to make my app doesn't run but it's ok now.

Java fatal error, don't know what it means

It happens at the same place in my code (albeit not the first time the method is executed) but I can't make head or tail of what is wrong. (Doubly so as it's code for a robot).
Be most appreciative if someone can give me an idea of what kind of problem it is. I assume it's to do with threading (multi-threaded app) but I don't really know what?!? Worried as deadline for uni project is looming!!!

The following error:
SIGSEGV (0xb) at pc=0xb70f0ca7, pid=5065, tid=2145643376
Shows that somewhere, you're accessing an invalid memory adress or NULL from process ID (5065) (not relevant at this moment).
So, if you're programming a robot, it means that you're either:
Using a library (DLL) that can communicate to a serial port to access that robot, your code to talk to the library is probably passing a NULL which in turn, crashes in the DLL.
Writing your own native library which then is accessing a NULL or invalid memory address.
The JVM then crashes. I can't help you further that this because I don't know how your programmed (in Java) to communicate to your robot so this is just an investigation.
Learn about SIGSEGV.

You are running Java 1.6.0 patch 15. The latest patch release (Java 1.6.0 patch 18) has fixes for a number of JVM crashing bugs according to the release notes. So it would be worth trying an upgrade.
However, the theory that your problems are caused by flakey JNI code is also plausible.
Here is some Sun documentation on Troubleshooting System Crashes for Java 6.
