    ESXI Reboot Troubleshooting

    rapid3642 Novice

      Hello, I am running ESXi 6.7 and I would love to learn how to troubleshoot the reboots that are occurring. Currently I only experience reboots when my Ubuntu VM is running and I try to play something on Plex. The transcoding almost seems to be too much for it but I have an AMD 8 core with 8gb of ram and no other VM or services running. I attached the support bundle that I generated just after a reboot. Any advice on things to check for or to help me and guide me into learning how to troubleshoot this issue is much appreciated.


      Server Specs:

      CPU: AMD 8150 8 core

      RAM: 8gb

      Esxi 6.7

      Running on standalone 5TB drive.


      Running VM's:

      Ubuntu server 18 running plex

      4 CPU's

      4GB of RAM

      Running on standalone 500gb drive.

      1 5TB USB external drive connected for storage.

          Is it a custom made server? That processor it's not on the HCL so this might cause you reboots.

          Do you have VMware tools installed on the VM?

            Thank you so much for the reply, yes it is a custom made PC (its a desktop really) I was running ESXI 5 on this server for years but then it started restarting randomly as of recently then I started making changes such as buying a new power supply (700w) new network card (intel p1000) swapped out ethernet cable with a new one, bought a new hard drive for the OS to sit on, installed ESXI 6.7 non modified. After all of these changes nothing seems to be helping the situation. I sort of threw money at it lol which is not a good solution, so now I wanna diagnose this the right way lol.

              I wold start thinking about checking the CPU seating and thermal paste. When was the paste last checked/changed?

              Swapping out memory modules and seeing if one of them has gone bad, or just needs reseating.
