After turning off "detecteur_de_vents.tcl" script (???), i restarted Eggdrop and i noticed that Eggdrop loads old scripts that shouldn't be loaded. I think it even runs scripts that actually doesn't exist in the script directory. Besides that every script is loaded twice as "Initialising scripts" log says.
My first thought is that one of your scripts may have some "autoload" feature, pretty much loading anything within your scripts-folder..
(There are a few scripts out there with this feature, that does'nt state it in it's documentation).
Indeed, disabling fsck.tcl made me realise that this one is the cause. Everything was clear after reading the introduction of fsck script. I just had to set LOAD_ALL_SCRIPTS to 0.
