Recibo el siguiente bloqueo de jvm cada pocos días al ejecutar Tomcat 6.0.16 en java 1.6.0_07.

El efecto es que Tomcat muere al instante.

¿Alguna idea de lo que esto significa?

An unexpected error has been detected by Java Runtime Environment:

 Java VM: Java HotSpot(TM) Client VM (10.0-b23 mixed mode windows-x86)
