OutOfMemory error when repetatively deploying and undeploying with 10 minute interval ------------------------------------------------------------------------------------- Key: JBAS-2299 URL: http://jira.jboss.com/jira/browse/JBAS-2299 Project: JBoss Application Server Issue Type: Feature Request Security Level: Public(Everyone can see) Components: Deployment services Affects Versions: JBossAS-4.0.3RC2 Environment: WinXP SP2, JBoss 4.0.3RC2, JDK 1.4.2_07 Reporter: Amar Syed Assigned To: Clebert Suconic Fix For: JBossAS-4.0.5.GA Attachments: Data.txt, SampleApp.ear 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 2005-09-24 06:04:31,413 DEBUG [org.jboss.mx.loading.RepositoryClassLoader] setRepository, repository=org.jboss.mx.loading.HeirarchicalLoaderRepository3@e51e50, cl=org.jboss.mx.loading.UnifiedClassLoader3@c90207{ url=null ,addedOrder=0} 2005-09-24 06:04:33,057 ERROR [org.apache.commons.digester.Digester] Begin event threw error java.lang.OutOfMemoryError 2005-09-24 06:04:33,057 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/XMPVXE0Partion/VXE1_ContentTestService]] StandardWrapper.Throwable java.lang.OutOfMemoryError 2005-09-24 06:04:33,057 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/XMPVXE0Partion/VXE1_ContentTestService]] Servlet /XMPVXE0Partion/VXE1_ContentTestService threw load() exception java.lang.OutOfMemoryError 2005-09-24 06:04:33,072 DEBUG [org.jboss.mx.loading.UnifiedClassLoader] New jmx UCL with url null The following two jars were added to the server\default\lib folder. commons-validator.jar --- version 1.1.3 struts.jar ---- version 1.2.4
