Shell script creating too many processes.

I have a shell script that I am running every 60 seconds, but it is creating this process to the point that it is causing the server to perfrom poorly. Below is my script, what can I change to prevent this?

while true
do
java -classpath .....( all my classes here)
>/dev/null 2>&1
sleep 60
done

what is your java program doing?

my java code is getting a list of work from web services, and based on that list runs a command to make files available to a user that requests it. If I run just the java code from command line, it runs once and then dies...a process that I repeated about 20 times from command line just to make sure I am not scheduling anything within the java.

So, I understand that process is not finishing before those 60 secs pass... I think that's the problem.
For instance, if you want it to be executed just 60 secs after it finishes, try something like:
Code:
while true; do
   java -classpath .....( all my classes here) >/dev/null 2>&1 && sleep 60
done

But be careful with this kind of loops. In this case, if the exit code of that java is not 0, the next execution would be inmediate.

Regards.
