Error starting Zabbix Agent

[gfreccia]

Hi!

I've set this on my zabbix_agentd.conf

UserParameter=icecast.global.clients,/usr/local/scripts/zabbix/icestats.sh clients
UserParameter=icecast.global.client_connections,/usr/local/scripts/zabbix/icestats.sh client_connections
UserParameter=icecast.global.sources,/usr/local/scripts/zabbix/icestats.sh sources
UserParameter=icecast.source.listeners[/parpeseggia],/usr/local/scripts/zabbix/icestats.sh mount-listeners $1
UserParameter=icecast.source.peak_listeners[/parpeseggia],/usr/local/scripts/zabbix/icestats.sh peak-listeners $1
UserParameter=icecast.source.slow_listeners[/parpeseggia],/usr/local/scripts/zabbix/icestats.sh mount-slow_listeners $1

I've this error starting the agent:
