Asterisk ending (0)

Hi,

We have several Asterisk installations where every so often, Asterisk exits without any apparent error occurring, or at least any being logged.

Has anyone else experienced this? Or can anyone provide any insight into what may have caused Asterisk to exit from the below information:
