dsh (distributed/dancer shell): remote processes keep running after stopping execution

[Developer Airpim]

I'd like an advise about a problem with "dsh": running some commands and then stopping it with "CTRL+C" I find some processes keep running on remote serves.

--------------------------------------------------

Here are the specs:

command:

dsh -M -g "servers" -c "tail -f /var/log/prefix*" 

having a group (see below) that point to three different servers with some "log files" starting with "prefix" (e.g. prefix1.log, prefix2.log, ...)

configuration files:

/etc/dsh/dsh.conf

verbose = 0 

remoteshell =rsh  

showmachinenames = 0

waitshell=1

/etc/dsh/machines.list

localhost

/etc/dsh/group/servers

root@server-1

root@server-2

root@server-3

note that from the machine running dsh, a password-less ssh connection to them is made through the use of ssh keys

The problem is that if I type CTRL+C to stop dsh, sometimes on some servers "tail" keeps running(!)
