Server crashed two times in 4 hours

Hi,

My server already crashed two times in 4 hours (i just bought it) i don't use any mods.

I feel like this a pretty high crash rate, and i don't want to keep going this way. Also when it crashes it doens't seem to save the constructions (might have to confirm that though) Is there anything i've missed?

Thanks in advance.

I only have one restart log.

When i say that the server crash i mean that nothing move in the server (except my self) and i cannot interact with the environnement (cannot kill dinos, gather ressources, equip weapons, etc...).
