Logstash shutsdown in less than 3 minutes with the below error:

[2018-11-01T23:49:50,288][ERROR][logstash.inputs.udp] Exception in inputworker {"exception"=\>#\<ZeroDivisionError: divided by 0\>, "backtrace"=\>["org/jruby/RubyFixnum.java:564:in `/'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-codec-netflow-3.14.1/lib/logstash/codecs/netflow.rb:268:in`decode\_netflow9'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-codec-netflow-3.14.1/lib/logstash/codecs/netflow.rb:124:in `block in decode'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/bindata-2.4.3/lib/bindata/array.rb:208:in`block in each'", "org/jruby/RubyArray.java:1734:in `each'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/bindata-2.4.3/lib/bindata/array.rb:208:in`each'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-codec-netflow-3.14.1/lib/logstash/codecs/netflow.rb:120:in `decode'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-input-udp-3.3.3/lib/logstash/inputs/udp.rb:142:in`inputworker'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-input-udp-3.3.3/lib/logstash/inputs/udp.rb:111:in `block in udp\_listener'"]}

I request community to help me to resolve this issue. I am using the elastic stack version 6.4.2
