The version I've been using is a dragino HE on a custom board
HEThe firmware is Dragino-v2 common-2.0.7
http://wiki.dragino.com/index.php?title=Yun_Firmware_Change_LogIt looks like there is now a newer firmware from the beginning of this year. I might give that a shot.. it looks like it has a newer version of CPU-MCU-bridge. I'm not sure if bridge is what is hanging up. When I do a reset-mcu command it appears to put everything on track for a couple weeks. Uptime is important in my application and the Linux side of things has chugged along for several months (when I last reset power). It's weird to me that it appears I'm having trouble with uptime on the MCU. Is there a changelog for bridge? It looks like the one on my install is only 1.6.0.
I believe the web files are stored on the sd card. I don't think I have a log or any other files that would eventually use up all the memory.
Why are you asking about an Arduino Yun when you are not using an Arduino Yun Board but a 3db party idea of an Arduino Yun Board? You should be asking about it on the Dragino Forums. Any answer we would provide would be invalid given that the answers would apply only to Arduino Yun boards and not Dragino HE module.
