Hi there,
The script I'm calling is not infinite but it can hang so it won't finish. That's why I force the timeout.
About the background, you made me doubt, as far as I know it's running in background but maybe someone more experienced could help us.
About the machine, mine is a Sun Ultra-60 sparc with Solaris 8 so I guess there's no problem
Regards!

As a side remark on stylistic issues, this

Code:
if [ `ps -p $PID|grep $PID|wc -l` -eq 1 ]

is better expressed simply as

Code:
if ps -p $PID | grep $PID >/dev/null

because grep will return true if there was a match, and false otherwise.

The redirection to /dev/null is because grep prints the matching line, which you don't want in this case. Many grep implementations also have a -q option which does the same thing.
