I observed another unexpected shutdown this morning, but this time (!) the error

 Login process died too early - shutting down

showed up in the logs. I'm using simple passwd-file and userdb-static
auth. The passwd file has not been changed during the night.

This _may_ be related to

I'm closely monitoring the system (now with 'ulimit -c unlimited') and
will report back if there are any news.
