logstash takes forever to run, even just 'logstash version'

Description

Logstash doesn't seem to ever fully start and collect logs. Doesn't even provide any stdout output after 10+ minutes.

even a simple `logstash version` takes a long time ( tried with both openjdk and oracle ) :

```
root@logstash-n01:~# time JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-amd64 /opt/logstash/server/bin/logstash version
logstash 1.4.1

real 2m50.969s
user 4m36.853s
sys 0m6.616s
```

I'm sure this is a problem with the server itself, rather than logstash code, but I haven't been able to track down anything that would suggest what is wrong.

It's a ubuntu 12.04 box, all packages updated.
32gb ram, 12core E5-2640 CPU

I've removed and reinstalled logstash, removed and reinstalled java.
