Not quite that easy to solve. In the case of a fatal error or resource starvation, that's a good recipe for a DOS against your system as it spins in a tight restart loop.

At the minimum you want a limit on restarts, possibly in a given time period. More realistically you should also consider some sort of increasing (possibly exponential) cool off period between restarts.
