Cause

Depending on the way a program terminates in Linux, it may or may not produce a core dump file. A core dump is a snapshot of the memory used by the program when it was terminated. An exact cause of the termination of the process can be ascertained using the steps outlined in Lessons Learned Entry 10975.

Resolution

To delete all the core dumps at once, type the following command:

rm -f `find / -name core.*`

The symbol before the word find is called a backtick. The backtick key is located to the left of the number one on a standard English-language keyboard.

To show a listing of all the core dumps on your computer, type the following command:

find / -name core.*

Once all the core files are deleted run the df command and verify the "Use%" of the /usr/local/Pelco directory is now below 100%. Then, reboot the machine by typing reboot and pressing ENTER.
