Ivan Masár commented on DS-1396: -------------------------------- BTW there's one strange thing I noticed in your setup - java-6-sun in path to java binary, but /usr/local/tomcat7 in classpath and elsewhere. It might not have anything to do with the issue, though. > Very slow startup on Linux Platforms > ------------------------------------ > > Key: DS-1396 > URL: https://jira.duraspace.org/browse/DS-1396 > Project: DSpace > Issue Type: Bug > Affects Versions: 3.0 > Environment: Linux version 2.6.32-38-server (buildd@allspice) (gcc > version 4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) > /usr/lib/jvm/java-6-sun/bin/java > -Djava.util.logging.config.file=/usr/local/tomcat7/conf/logging.properties > -Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom -Xms256m > -Xmx800m -XX:PermSize=256m -XX:NewSize=64m -server -XX:+UseConcMarkSweepGC > -Djava.net.preferIPv4Stack=true > -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager > -Djava.endorsed.dirs=/usr/local/tomcat7/endorsed -classpath > /usr/local/tomcat7/bin/bootstrap.jar:/usr/local/tomcat7/bin/tomcat-juli.jar > -Dcatalina.base=/usr/local/tomcat7 -Dcatalina.home=/usr/local/tomcat7 > -Djava.io.tmpdir=/tmp/tomcat7-tmp org.apache.catalina.startup.Bootstrap start > Reporter: Ian Boston > Priority: Critical > > I am experiencing extremely slow startup times for DS3-rc3 on Linux with the > stock sun JVM, and I have experienced total hangs 11:19-15:09 of the JVM with > perfect operation after the end of the period (no restart of any form was > required).
