      Hi,

       

      I am trying to take heap dump and I have configured this "-XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=$JBOSS_HOME/server/heapDumps/" in run.conf. When I am trying to use the command "kill -3 <PID>, still it is generating the dump on the console itself. So can some one please guide me how to redirect this even on using "kill -3 <PID>"

          Hi,

           

          if you are using run.sh you should redirect the STDOUT and STDERR to a file

          e.g.

          bin/run.sh -c default 2>&1 >server/default/log/start.log &

            The HeapDumpPath is used only when a heap dump is performed on an out-of-memory error, it is not used when you signal for a head dump. Besides, this functionality is entirely based on the JVM (JBoss AS has noithing to do with it), so you might try asking the supplier of your JVM about this (which I assume is Oracle).
