rsh command

Unable to get rsh executed in loop correctly?

We are developing a monitoring script that uses rsh to login to our servers to check if a process based on log file has completed by set time and to check health of systems. The script executes a health check on remote server and writes to consolidated file. The script is successful if we execute the rsh calls directly in file such as
rsh server1 check_server.ksh >> outfile 2>&1
rsh server2 check_server.ksh >> outfile 2>&1 . . .

However, if we read a file with all the servers and execute the rsh the script only does the first rsh to server and ignores others. When we take the rsh command out, we replace with echo $server which prints out correctly all servers in file.

cat $file | while read server
do
echo $server
rsh $server check_server.ksh >> outfile 2>&1
done

Any ideas to help us why rsh will not work in loop?

Thanks
