3 x /opt/rudder/bin/perl process at the same time
Regression:
Description
I thought it was not possible to have more than one "rudder-agent" at the same time, but my "ps fax" said it's possible. As you know my nodes are very light (RAM 512Mo, single ARM core) so complex perl script are not my friend.
This processes (below) were on the same time, the first come from my own command in crontab where I run "rudder agent run", the 2 others are the official rudder processes.
In resume 3 perl process for inventory in the same time...

Thee reasons here:
- the last one is the one that is launched normally once a day
- the second one is just a call used to retrieve the version (since it could have been provided by the system and old versions have some specific parameters)
this one is done in the system technique in inventory/1.0/fusionAgent.st line 176
- The first one is due to the fact that rudder agent run is a command that remove lock detection, since it has been made for people who want to force a run, so it ignores the fact that there is another one currently running
Maybe we should add an option to rudder agent to change this behavior.
What do you think ?
