dedicated server cyclic restarts

my dedicated server has been restarting itself after "game ready" but before "session loaded" today. i have restarted the hardware server and attempted roll backs to before the issue began to no avail. i have disabled in-game scripts and the issue persists. the last bit of log that i have in the SpaceEngineersDedicated_20200429_161223938.log reads:
