I created two Store procedures to time table scheduling some months back and test it at the time which was fine. The first procedure has a cursor to navigate a list of records and call the second procedure. The Second Procedure has two cursors for different scenarios.

Now trying to a final test before moving to production and it crashes my MariaDB Server mid way. Even when I called the Second Procedure individually with static parameters, after three to five calls MariaDB still crashes.

The Operating system is Centos 6.6, MariaDB 10.0.21 and error from log displays is as follows

I also did a test on MariaDB 10.0.17 on windows still no luck.
