I have been investigating a Logstash issue with the file input on windows 7 x86.

Se this JVM error log at https://gist.github.com/ph/c0dcc55573337a8d2296

When we try to use the File::Stat.new on a file deleted by another process it
throw an exception EXCEPTION_PRIV_INSTRUCTION by following the trace and the logic flow I have narrowed it down in our code to this line https://github.com/jordansissel/ruby-filewatch/blob/master/lib/filewatch/watch.rb#L102

Few points that I know:

• When I run the same code in a Windows 2012 Server or Windows 10, I don't have the problem.
• When I rollback to JRuby to 1.7.22 I don't see the issue anymore on windows 7.

I have tried to create a simple test case outside of Logstash without luck so far.
I have a reproducible way using logstash check the issue for the full test case
