Linux + bash + redirect output of command to /dev/null

I run the following line from my bash script in order to run the script /usr/run.pl on remote machinemachines

  xargs -P "$numprocs" -I '{}' -n  1 -- perl -e 'alarm shift; exec @ARGV' -- "$timeout" ssh -nxaq -o ConnectTimeout=5 -o StrictHostKeyChecking=no '{}' /usr/run.sh < <(echo -e "$node")

but I get on the console the following standard output

Connection to 143.6.22.4 closed by remote host.
 xargs: perl: exited with status 255; aborting

where I need to put the 1>/dev/null in my syntax to avoid this message?
