[Minecraft Server Crashes After a Few Minutes (FORGE ONLY)]

Hello, same problem for me, my server crash many times during games and crash many times a row ( 2 to 3 times yesterday).

I don't think this crash is generated by mods because it works correctly locally.

 

Crash-report : (for anonymity i remove players names)
