I used this script long ago and got something like 2600 MiB as the max I
could use. I just tried it (moved to a VM recently) and it never
returned a valid max heap. Something might be wrong with the script or
the (hardware) VM configuration.
#!/bin/sh
initial_max=4097
max=${initial_max}
return_value=1
while [ "1" == "$return_value" ] ; do
max=`expr ${max} - 1`
if [ "0" == `expr ${max} % 100` ] ; then
echo "(max=${max})"
fi
java -Xms${max}M -Xmx${max}M MemoryInfo > /dev/null 2>&1
return_value=$?
done
echo
echo Stopped with max=${max}
echo Return value was ${return_value}
