[jira] [Commented] (QPID-6283) FileSystemSpaceChecker can generate
java.lang.ArithmeticException / by zero
[ https://issues.apache.org/jira/browse/QPID-6283?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14256773#comment-14256773 ]
Keith Wall commented on QPID-6283:
----------------------------------
Problem is seen to occur (on Mac OS X) when the files belonging to a vhost are removed whilst the virtual host is still active. This wouldn't normally happen outside a development environment. (I have in my case I run a mvn clean whilst the Broker was still up).
