Starting EAP 6 RPM install sometimes falsely reports "Process crashed on startup"

Issue

• We've installed EAP 6 from the RPM. Starting up sometimes we see "Process crashed on startup" immediately.
• This occurs because multiple pids are unexpectedly seen at the below lines in the service script:

    echo `pidof -x "$JBOSSSH_only"` > $JBOSSPID
    read ppid < $JBOSSPID
    if [ ! -z $ppid ]; then
       if [ `ps --pid $ppid 2> /dev/null | grep -c $ppid 2> /dev/null` -eq '1' ]; then

• The child process being started up is still seen at this line in a state similar to the parent process as it is being forked:

16498 ?        S      0:00 $EAP_HOME/bin/CLOUD_0000.sh -P standalone.conf-c standalone-full-ha.xml
16593 ?        S      0:00  \_ /$EAP_HOME/bin/CLOUD_0000.sh -P standalone.conf -c standalone-full-ha.xml
