Unless you have lot of other things running (you shouldn't, use a server dedicated to Alfresco), try increasing to -Xmx6G (you said you had a total of 8, so why not use as much as possible).

You can also check if it is the java process that consumes, sometimes it is Libre Office (soffice.bin). I've seen it get stuck in transformations, just kill it and see if it helps. You can use this script to start/stop Libre Office without restarting Alfresco https://github.com/loftuxab/alfresco-ubuntu-install/blob/master/scripts/libreoffice.sh

I have stopped soffice and increased ram to 6gb still no change.
