I am trying to use IP2Location ruby client with jruby
http://ip2location.com/developers/ruby. Resolving IP address to geo location in
loop fails consistently after 5070 iterations. Sometimes I get SIGSEGV from JVM
:(

# A fatal error has been detected by the Java Runtime Environment:
#
# SIGSEGV (0xb) at pc=0x00007f105cace000, pid=602, tid=139708317136640

# JRE version: 6.0_26-b03
# Java VM: Java HotSpot(TM) 64-Bit Server VM (20.1-b02 mixed mode linux-amd64
compressed oops)
# Problematic frame:
# J org.jruby.RubyBasicObject.getRuntime()Lorg/jruby/Ruby;
