Hey all
I have a problem with a program
You see, I have a python script made in Python 2.2 that runs every 15
minutes on Linux Red Hat 9.0
This program (which code is attached below) named levantamuertos.py (spanish
for death weakener) has to check in a database if the pids stored are
running (note that it will be more than one pid) and if they are not it has
to start again the process and it will store the new pid on the database
The problem is that when I call it it runs and weaks all dead process but
when it dies, he takes all his sons with him.
How can I make that the cotascamon.py keep running although
levantamuertos.py die?
Thanks in advanced and here is the code
Alberto
