OK, the box crashed again, two times.  For the first crash I don't have
a failure message neither a crash dump.  The second crash is as follows:

Seems its somewhat related to HAMMER?!?  The fs is not full, there is
plenty of space left ... just in case someone wants to know:

ad10s2         9.8G   2.1G   7.7G    22%    /hammer
