redhat 7 create a core dump file

[jlim0930]

I am trying to create a core dump file from a process that is failing every few days.

so far i have been looking at the gdb but really cant figure out how to use it to write a core dump file..

any suggestions ?

if you are facing a problem something like

Program just crashes with "segmentation fault ../../../Source/xx >>xx.cerr"
No dumps are created.

you can force the linux to create the dump file by


setting up your console to ensure that dumps are created...

The command is ulimit -c 50000 where 50000 is the size in bytes.
