mysql crash right after a startsystem completed - At least one DBRoot required for that query is offline

Nightly regression test log showed a lot of query failures.

Log file showed the reason as :

crit.log-20160510:May 9 21:10:51 srvregtest joblist[17423]: 51.234265 |2147483653|0|0| C 05 CAL0000: IDB-2034: At least one DBRoot required for that query is offline.

Logs files showed that a startsystem just completed and mysql crashed right after the system went active.

Server version: 10.1.10-MariaDB
key_buffer_size=536870912
read_buffer_size=4194304
max_used_connections=2
max_threads=153
thread_count=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1780770 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
