title: Java Hotspot Error - V [libjvm.so+0x5c3a84]
body: <p>I am having real problems getting to the bottom of the java hotspot errors we are experiencing. The errors are seemingly random and the problematic frame varies. An example error is shown below: </p>
  
  <pre><code>#
  # A fatal error has been detected by the Java Runtime Environment:

  <p>The java application is a relatively simple, it is just a war file running in a tomcat on a server. </p>
  
  <p>Please let me know if any additional information would be helpful to access, I'm a bit new to this. The current thinking is that this is a hardware issue but any further information would be much appreciated. </p>
  
  <p>Thanks,
