I have come to the conclusion [through some experimenting and trials] that the cause of the recent server crashes (the ones that happened this evening and were only down for a minute or so, but were frequent) are because someone somewhere is opening a wooden crate. The server happened to crash every time I open my wooden crate, exactly when I tried. I tried this two or three times to confirm and then realized it was me who was crashing the server (sorry about that ) But I am letting everyone know that wooden crates crash the server and should not be opened!
