core dumps
Enable core file dumps for third party application on Red Hat 6 Server (In Red Hat Enterprise Linux core file creation is disabled by default.)
Ensure that the system is set up to generate application cores by removing the core limits:
# ulimit -S -c unlimited > /dev/null 2>&1
Stop the abrtd deamon (core dumps for Red Hat applications):
# service abrtd stop
# service abrt-ccpp stop
For Red Hat 7 and later:
# systemctl stop abrtd.service
# systemctl stop abrt-ccpp.service
Core files are created in the application working directory.
Run core with gdb
# gdb <application> -c core.<pid>
# gdb where
