Steve Jagels [https://community.jboss.org/people/sej] created the discussion "java heap space" To view the discussion, visit: https://community.jboss.org/message/749949#749949 -------------------------------------------------------------- I've been using eclipse 5.5.1, but I recently went to a new machine and I've been asked to go to MyEclipse 10.5.  Code that was running fine in 5.5.1 is now getting a java heap space error in 10.5.  The 10.5 eclipse.ini file has: #utf8 (do not remove) #utf8 (do not remove) -startup ../Common/plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar --launcher.library ../Common/plugins/org.eclipse.equinox.launcher.i18n.win32.win32.x86_64_4.2.0.v201201111650 -install C:\Java\MyEclipse10.5\MyEclipse 10 -vm C:\Java\MyEclipse10.5\Common\binary\com.sun.java.jdk.win32.x86_64_1.6.0.013\bin\javaw.exe -configuration C:\Java\MyEclipse10.5\MyEclipse 10\configuration -vmargs -Xmx512m -XX:MaxPermSize=256m -XX:ReservedCodeCacheSize=64m -Dosgi.nls.warnings=ignore So I decided to bump up some of the numbers: -Xms1024m -Xmx2048m But I still get the java heap space.  And I've tried upping the MaxPermSize and ReservedCodeCacheSize and those do not fix anything. When I remove the sql driver file from the jboss lib directory, I no longer get the java heap space error, but of course then I get a different error because it does not find any driver file. So any ideas for this? I'm using jboss 4.0.4 and jdk 1.5.0.17. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/749949#749949] Start a new discussion in Beginner's Corner at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
