[syslog-ng] Routers don´t send syslog

Mrs, I have a lot of Routers configured to send logs to syslog-ng, but isn´t work. Only 1 router send ok, others 10 not ok. My configuration on routers is the same: service timestamps debug datetime msec localtime show-timezone service timestamps log datetime msec localtime show-timezone logging <my ip> logging buffered 10000 debugging logging trap debugging I check with command : show logging And it´s ok, for me. Anyone have a problema with routers? Thanks, Dud.
