Alfresco GC overhead limit exceeded - out-of-memory

Question

I have still this problem , I read all the others forum posts about the problem but no one said how to fix, I run alfresco as a windows service on windows server.
Here is my value data:
-Xms1G
-Xmx4G
-XX:MaxPermSize=1G
-XX:-DisableExplicitGC
-XX:ReservedCodeCacheSize=128m
-Dalfresco.home=C:\Alfresco
-Dcom.sun.management.jmxremote
-Dcatalina.home=C:\Alfresco\tomcat
-Dcatalina.base=C:\Alfresco\tomcat
-Djava.endorsed.dirs=C:\Alfresco\tomcat\endorsed
-Djava.io.tmpdir=C:\Alfresco\tomcat\temp
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=C:\Alfresco\tomcat\conf\logging.properties
System ;
Processor : 3.40 GHz
RAM : 8.00 GB
System type : 64-bit

Answer 1

Check the size that you have set for JVM in alfresco.bat/alfresco.sh.
Increase 128 to 256 and 512 to 1024, if you have enough RAM available in your server then try again.
