[Thiago Hernandes (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-3432?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12972595#comment-12972595 ] 

Thiago Hernandes commented on WFLY-3432:
----------------------------------------

I solved this with:

Wildfly 8.0 and 8.1
---------------------------------------------------------------------------------------
java.lang.OutOfMemoryError: Java heap space
---------------------------------------------------------------------------------------

Solution to Perm Gen Memory, overflow of memory etc...

In file: standalone.conf (/wildfly8.1/bin) at the block:

if [ "x$JAVA_OPTS" = "x" ]; then
   JAVA_OPTS="-Xms64m -Xmx512m -XX:MaxPermSize=256m -Djava.net.preferIPv4Stack=true"
   JAVA_OPTS="$JAVA_OPTS -Djboss.modules.system.pkgs=$JBOSS_MODULES_SYSTEM_PKGS -Djava.awt.headless=true"
else

Replace with (to machines with 4GB RAM):

if [ "x$JAVA_OPTS" = "x" ]; then
   JAVA_OPTS="-Xms512m -Xmx2048m -XX:MaxPermSize=2048m -Djava.net.preferIPv4Stack=true"
   JAVA_OPTS="$JAVA_OPTS -Djboss.modules.system.pkgs=$JBOSS_MODULES_SYSTEM_PKGS -Djava.awt.headless=true"
else

Important notice that 156 initial value, 1024 max value and another 1024 the Perm max size. 

It´s possible to increase this values when server configurartion´s is more powerful
