I have a mango es that I upgraded to from v2 to v3. It was originally stopping because it was in demo mode, but it now has a paid license on it. Every couple days since I put it into production the core just stops running. The ES is still on, I can access webmin and DGLux 5 server keeps running. The logs just stop running and don't show whats happening. I can start Mango again and its run fine until it stops again.
Where should I start looking?
