Hello, I have a problem since my server is 1.4. Several crash happen from time to time, I do not know why. However, I think I have made the majority of plugins to date, but the crashes still occur, and we can not even know where it comes from because there is no error message in console or in logs . The process on my Ubuntu server turns off.
