I am using my Ubuntu to do some programming assignments at college and it keeps hanging.
For example,
If I have an infinite loop in my C code by mistake, Ubuntu freezes.
If my C program allocates memory at runtime and I give it a large dataset by mistake, it freezes.
If I switch on RStudio and run a very memory intensive function - it freezes.
By "freeze" I mean that the GUI stops changing, mouse stops moving, keyboard doesn't work. Cannot even go into other ttys using Ctrl+Alt+F1
This never used to happen on the windows computer I was using before (and that was 32bit while my current laptop is 64bit)
It seems as though the process I'm running takes up 100% memory/cpu and hence nothing else works. How do I limit the amount of memory and cpu that each process can take ?
I checked a little on limits.conf but I was unable to find what exactly to do in the limits.conf file nor could I find what limits are considered "safe"
