How to resolve "GC overhead limit exceeded" error


Increase the Jaba heap.  

Set it as JVM arguments the usual way, e.g. -Xms1024m -Xmx2048m for a minimum heap of 1GB and maximum heap of 2GB. JBoss will use the JAVA_OPTS environment variable to include additional JVM arguments, you could specify it in the /bin/run.conf.bat file: 

set "JAVA_OPTS=%JAVA_OPTS% -Xms1024m -Xmx2048m"
