> Using a manual copy and delete mechanism with the server\default\deploy folder the sample ear (attached) caused an outofmemory error eventually after 90 repetitions.
> The min and max heap settings were configured as : -Xms128m -Xmx512m
> The time delay after dropping/deploying the ear at each repetition was set to 10 minutes after which the ear is deleted/undeployed followed by a 10 second sleep till the next deploy cycle.
> I find this behaviour strange because http://jira.jboss.com/jira/browse/JBAS-1319 is supposed to have fixed this issue.
> The lines from the server.log surrounding the java.lang.OutOfMemoryError are as follows:
> 2005-09-24 06:04:31,413 DEBUG [org.jboss.mx.loading.UnifiedClassLoader] New jmx UCL with url null
