Hello,
I'm getting below error in logstash and then logstash crashes.
NoMethodError: undefined method `map_cleanup' for nil:NilClass
start at /appl/logstash/vendor/bundle/jruby/1.9/gems/logstash-codec-multiline-2.0.11/lib/logstash/codecs/identity_map_codec.rb:55
I have installed ELK in 4 servers.. 2 for production and 2 for QA..
I'm getting the above error only on one server in QA .. In remaining boxes logstash instance is working absolutely fine without any issue.. that surprises me al lot..
Can I get a help for this issue.. ?
Thanks
Fredrick
