This morning, I tried command "kill -7 [pid]" but didn't see the core
file. Anybody has ideas?
do the following before starting your program :
# ulimit -c unlimited
You can check before and after that the core size changed from 0 to
"unlimited" :
# ulimit -a

Thank you very much. The command "kill -7 [pid]" really works with
"ulimit -c unlimited"
