If you are using Maven on hudson for continuous integration and if there is a error for outofmemory then

• Navigate Hudson -> [project] -> configuration
• Build -> Invoke Maven 3 -> JVM option
• put following parameter in that property                                                 -Xmx1024m -XX:MaxPermSize=256m -XX:+DisableExplicitGC

Other way is you can set following in mvn file
export MAVEN_OPTS="-Xmx1024m -XX:MaxPermSize=256m -XX:+DisableExplicitGC"
