the same message kept coming up 3-4 times per second
tried to run the configuration with the service (put it in /etc/logstash/conf.d)
and the service crashed after 3 second (no logs - tried to run the service with debug and still no logs)
now al the other configurations that have worked before don't work now - the service always crashes
tried to change LS_HEAP_SIZE -still didn't work
tried booting the server twice - no help
tried to reinstall logstash - no help
what to do ????
