I'm seeing a couple issues, you'll want to contact Tableau Technical Support to troubleshoot directly.
1. This is a 4 core computer. If you want to run more than 1 of each process, I recommend meeting the minimum recommended requirements of an 8 core computer with 64GB of RAM: All Technical Specifications | Tableau Software
2. Your gateway is running on port 8040. The default gateway port is 80. Is there a reason this has been moved? The failure to start may have to do with this custom port being unavailable.
