What cause my process to be killed?

I am using Matlab inside Ubuntu 11.10. many times when I tried to run it, it will be closed and and strange message appears on terminal :"Killed". I really do not know what cause this problem. by the way I have modified lib64 with commands below : sudo ln -s /lib/x86_64-linux-gnu/libc-2.13.so /lib64/libc.so.6 but the program is killed again. However, I also do not think think that the problem is because of program, because I have it tested on Matlab inside windows systems without problem.

What happens if you launch it without java and the desktop?

matlab -nojvm -nodesktop

[smabtahi]

the same thing happened. only writes " killed".

[Walter Roberson]

Sounds like it is time for strace or ptrace .

I got the same issue running it on Ubuntu 15.10 with the -nojvm option

Same thing happend to me in Ubuntu 20.04. Tried 4-5 times to run a simulink code in normal mode, accelerator mode, and rapid acceleration mode. In every case Ubuntu self kills matlab after 10 hrs.

I got the same issue on Ubuntu 20.04. I was trying to run a simulation based on 5G toolbox. MATLAB crashed after runing for around 10 hours and only left a 'Killed' on the terminal. It has been more than 10 years since this question posted.

I've also experienced this while running scripts with long loops. No explananation beyond "Killed" in the terminal.
