I'm just installed logstash 1.5.1 on a similar VM to one that runs logstash 1.4.2 without issue. On the new VM, however, logstash 1.5.1 crashes on startup with the following error logs:
NotImplementedError: stat.st\_gid unsupported or native support failed to load

Any ideas what the issue might be? I'm trawling through the code now, but I don't know ruby so it's slow going.

I'm getting closer. It is _creating_ the .sincdb files, but writing nothing into them...

Sometimes I get the following error instead:

That's pretty unusual, I'll ask an LS dev to comment.

Hi, we've seen this issue in Ubuntu 14.04 and Oracle JDK. This is not a Logstash issue per se, but a JDK platform issue. The workaround mentioned in the github issue works for most folks. See [https://github.com/elastic/logstash/issues/3127#issuecomment-101068714](https://github.com/elastic/logstash/issues/3127#issuecomment-101068714)

Thank you, that's exactly what I needed
