Fatal in logstash 6.0.0

Elastic Stack Logstash

Hi all,
i receive the following error in logstash logs and the process died.:

Error: unknown IOException: jnr.enxio.channels.NativeException: Error closing fd 371: Stale NFS file handle
Exception: Java::JavaLang::RuntimeException
Stack: org.jruby.util.io.PosixShim.close(PosixShim.java:260)
.....
.....
[2018-01-08T01:26:50,814][FATAL][logstash.runner ] An unexpected error occurred! {:error=>#<NoMethodError: undefined method map_cleanup' for nil:NilClass>, :backtrace=>["/export/home/elastic/logstash-6.0.0/vendor/bundle/jruby/2.3.0/gems/logstash-codec-multiline-3.0.7/lib/logstash/codecs/identity_map_codec.rb:55:inblock in start'"]}

I don't know the cause, can someone help me to solve?

The second FATAL error logged is a known rare case that is logged during shutdown.

The Stale NFS file handle exception seems to be causing the LS shutdown.

What is your config? Where is NFS being used?

LS in my config has 1 beats input and several file input, a grok filte with date and mutate and several output configs. 4 gb of heap, 16 worker (i have 16 cpu) and 250 pipeline.batch.size.

With file input i read from an nfs share....

There are known problems with the file input and NFS.

Missing event - file input plugin / NFS - #19 by steffens (with input from the LS and Beats teams)

You should put Filebeat on the machine that the NFS share points at.
