Hi.

We are using NetApp NFS mounts on RedHat 7.6. The NetApp storage is setup as tamper proof storage with SnapLock Volume Append Mode (VAM) activated. The Logstash file output can write for a short while, then crashes with an unknown error at,

> :backtrace=\>["org/jruby/RubyIO.java:1457:in `write'", "org/jruby/RubyIO.java:1428:in `write'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-output-file-4.2.6/lib/logstash/outputs/file.rb:374:in `write'"

Any suggestions what to do?

Best Regards,  
Bjorn
