SSH Script is sticking, & sign not doing what I would expect
I am having an issue where I am do an SSH to about 30 servers one at a time however my script is getting hung up sometimes on the SSH.
I thought the & at the end as seen below would fire it and move on but that does not seem to be working.

Code:
#!/bin/s
for remsys in trumpetsnail angel delphin kraken bluemarron penguinshrimp moccasin roughgreen bluegarter eastindigo penribbon ringneck banded bl
ackracer applesnail skimmerclam seaclam
        do
        /lcl/tools/bin/sshPing.pl $remsys
VAR=$`/usr/bin/ssh $remsys "/lcl/apps/Tivoli/netcool/omnibus/bin/syslog_mon.sh" 2>&1 &`
Results=${VAR}
echo $Results
done

Any ideas?
