Description

I have a keyboard application shortcut defined to run a shell script that brings up four SSH sessions like this:

xfce4-terminal -e "ssh host1" xfce4-terminal -e "ssh host2" xfce4-terminal -e "ssh host3" xfce4-terminal -e "ssh host4"

When I press the keyboard shortcut, four terminal windows are opened if the system is lightly loaded, but if the system is under heavy load eight terminal windows are opened. There are two instances of each host of the four hosts: two instances of host1, etc.. It is as though my shell script is executed twice.

I also see the same behavior when I type an application shortcut that launches just one SSH session:

xfce4-terminal -e "ssh host1"

When I press the shortcut keys under light load, one session is opened, but under heavy load two sessions are opened.

In either use case it appears as though the action associated with my application shortcut is taken twice if the system was under heavy load such as disk I/O.
