Computers shut down on server randomly. Havent tracked down cause yet.

[cadergator10]

I run a small scp community on minecraft, and the way we use opencomputers are for the security system. Everyone has a card and they swipe it on a magreader, and it lets them in and such. But randomly, all the computers just shut down in the site. We are currently building, so it isnt much of an issue yet, but with maybe over 50 different computers in the site soon, THIS HAS TO BE FIXED! Any suggestions on how it can be fixed?

I use magma on the server, and have daily restarts

Could it be something with how the computer might be constantly waiting for an event? (It can maybe go for a whole day waiting for an event)

Look for any OC related lines in the server log. On our server OC couldn't save the state of some computer. Because of that those computers were off when the chunk reloaded.
Our solution was to use a redstone clock to reboot the computer.

In a crash log, I did receive an error that a computer block was corrupted, but it only happened once. What causes a computer to be unable to retain its state? I don't want to have all the computers on chunk loaders

I discovered the error

I really, really need a fix for this :/ It makes the card system unusable if it constantly powers off the computer

I think this might be fixed in newer dev builds. You can get them from the CI server
