Subject [jira] Commented: (AMQ-1170) ActiveMQ fails to start correctly when hostname changed
Date Tue, 01 Jul 2008 20:50:00 GMT

    [ https://issues.apache.org/activemq/browse/AMQ-1170?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=43846#action_43846
] 

Hans Bausewein commented on AMQ-1170:
-------------------------------------

Maybe it's a JVM problem (or is it a feature?).

Set  JVM environment property "sun.net.inetaddr.ttl" to avoid DNS caching.

See http://java.sun.com/j2se/1.5.0/docs/guide/net/properties.html#nct


But if all JVMs have been shutdown, there cannot be anything cached.
