Java heap warning... How can I get rid of it?

[meansartin14]

When I start Alfresco, there are 15 INFO lines, 2 WARN lines and 0 ERROR lines.

Here's a full copy of output to alfresco.log upon startup:

I am particularly interested in fixing the following line:

11:09:20,875 WARN  [org.alfresco.service.descriptor.DescriptorService] Alfresco JVM - WARNING - maximum heap size 455.125MB is less than recommended 512MB‍

How do I get the Java maximum heap size back to 512? I have never run into this problem before.

Open alfresco\alfresco.bat file and change line JAVA_OPTS=-Xms128m –Xmx256m -Xss96k -XX:MaxPermSize=128m –server to JAVA_OPTS=-Xms128m –Xmx1024m -Xss96k -XX:MaxPermSize=128m –server

Open alfresco\alfresco.bat file and change line JAVA_OPTS=-Xms128m –Xmx256m -Xss96k -XX:MaxPermSize=128m –server to JAVA_OPTS=-Xms128m –Xmx1024m -Xss96k -XX:MaxPermSize=128m –server

Worked perfectly. Thank you very much!

Two minor notes:
   1) I edited alfresco.sh, not alfresco.bat (I'm using a RHEL 5.2 server)
   2) In alfresco.sh, there is no ""-Xss96k" option. As such, I changed my JAVA_OPTS as follows:
alfresco.sh went from this:

…
export JAVA_OPTS='-Xms128m -Xmx512m -XX:MaxPermSize=128m -server'
…‍‍‍

TO THIS

…
export JAVA_OPTS='-Xms128m -Xmx1024m -XX:MaxPermSize=128m -server'
