Before posting something, READ the changelog, WATCH the videos, howto and provide following:
Your install is: Bare metal, ESXi, what CPU model, RAM, HD, what EVE version you have, output of the uname -a and any other info that might help us faster.

ESXi 8.0 U3 becomes unresponsive when EVE runs

Post by mvanoverbeek » Sun Aug 03, 2025 3:33 pm

I just purchased EVE-NG Pro to help with customer labs I would like to build. The server installed properly, and I tested it out with an Aruba AOX-CX switch which works fine.
The problem I run into is that my ESXi 8.0 Update 3 becomes unreachable after a while. Potentially through a CRON job that runs every night because every morning I wake up the box is unreachable. This ONLY Happens if EVE is running. When I shutdown the EVE VM the machine runs fine and the server does not become unreachable over night.

My specs are:
CPU: 16 CPUs x AMD Ryzen 9 5950X 16-Core Processor
Memory: 127.92 GB
Storage: 2TB NVME

I allocated to EVE::
Sockets: 6 with 2 CPUs per socket = 12 CPUs
RAM: 48 GB
Storage: 300 GB

Does this sound familiar to anyone? Appreciate some guidance>
