Photon Server Self Shutdown Issue

Hi, I've had no issues with our game server until recently. We've had 3 server self shutdowns in the past 2 weeks and I'm not sure what is causing the shutdowns.

Here is the basic configuration:


I have an unlimited CCU license
Our peak CCU around the time of the crashes is about ~900.

Here is the server log prior to the shutdown:

  • hi, @trungmmm

    this could happen if you have stack overflow, or you have updated some files in server folder.
    Please provide us full logs from bin_Win64/logs

    best,
