UDP listener died. IOError: closed stream

Elastic Stack Logstash
1

Dear community,

I'm evaluating logstash and stuck on this problem with a UDP Input.
The part of config
input {
udp {
port => 9995
type => "netflow"
}
}
Logstash version is 2.2.2
OS is Centos Linux 7, selinux is disabled.

Firewall port is open

firewall-cmd --zone=dmz --permanent --list-ports

1514/udp 9995/udp 1514/tcp 9997/tcp

Trace:

{:timestamp=>"2016-03-10T13:02:31.930000+0300", :message=>"UDP listener died", :exception=>#<IOError: closed stream>, :backtrace=>["org/jruby/RubyIO.java:3682:in select'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-input-udp-2.0.3/lib/logstash/inputs/udp.rb:77:inudp_listener'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-input-udp-2.0.3/lib/logstash/inputs/udp.rb:50:in run'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.2.2-java/lib/logstash/pipeline.rb:331:ininputworker'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.2.2-java/lib/logstash/pipeline.rb:325:in `start_input'"], :level=>:warn}

Please, help me to workaround the issue.
Thank you.
