Please always mention which software version you run and how the system is deployed
and if there is anything special in the network.
In general it is not expected for a system to reboot itself. Also with newer software versions
I would in most cases not expect that as it should go into maintenance mode.
You can always check in the bug toolkit if you find any notes which could cause a reboot.
I would start with using a recent software version. TC6.3 seems to be more stable to ma than. TC7.0.2
If the problem remains try to limit issues, like disconnect the network and other connected components
to see if it still happens.
If you have a service contract think about opening a TAC case for it.
