I installed Alfresco Community 4.2.0c (manual install) with these Tomcat settings in startup.sh:
CATALINA_OPTS="-Xms512m -Xmx1024m -Xss1024k -XX:MaxPermSize=900m -XX:NewSize=512m -server -Dalfresco.home=/home/aegif/alfresco -Dcom.sun.management.jmxremote"
On Oracle jdk1.7.0_15, Linux 2.6.18, CentOS 5.8.
When I launch startup.sh, Alfresco starts running, but a minute after the Alfresco started message, I get:
Apr 15, 2013 7:17:32 PM org.apache.catalina.startup.HostConfig deployWARs
SEVERE: Error waiting for multi-thread deployment of WAR files to complete
java.util.concurrent.ExecutionException: java.lang.OutOfMemoryError: PermGen space
How can I get this error even though MaxPermSize=900m which is already a huge value?
By the way, I get the same exception with other MaxPermSize values like 256m or 700m.
Hint: The log says:
maximum heap size 247.500MB
WARNING - maximum heap size 247.500MB is less than recommended 512MB
Even though startup.sh has -Xmx1024m.
Is my CATALINA_OPTS wrong?
It appears that its taking the CATALINA_OPTS value from somewhere else, have a look at catalina.sh also try to put/define these settings in catalina.sh instead of startup.sh.
