Just the one burp? In which case we're OK (if there was a steady player load).
edit: sure enough the console window is exactly where I left it last night after that burp, meaning it has not burped since.
Freighter production is disabled, the probablility is set to 2.0 (on a 0-1 scale where 0.01 is a high prodcution probablilty and 0.99 is a low production propbablilty).
I can try increasing freighter production probablilty to 0.98 from 2.0 to see if that helps...
