This could be because you hit a bug. It is also possible that this binary

or one of the libraries it was linked against is corrupt, improperly built,

or misconfigured. This error can also be caused by malfunctioning hardware.

To report this bug, see https://mariadb.com/kb/en/reporting-bugs

We will try our best to scrape up some info that will hopefully help

diagnose the problem, but since we have already crashed,

something is definitely wrong and this may fail.

Server version: 10.3.6-MariaDB-debug-log

key_buffer_size=1048576

read_buffer_size=131072

max_used_connections=3

max_threads=153

thread_count=9

It is possible that mysqld could use up to

key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 61986 K  bytes of memory

Hope that's ok; if not, decrease some variables in the equation.

Thread pointer: 0xa79081b0

where mysqld died. If you see no messages after this, something went

terribly wrong...

Attempting backtrace. You can use the following information to find out

According to the "Cross Reference Report" first failure of this kind happened in bb-10.3-marko on rev. f0e4f94c230326a2f2e608e4119530d7 2018-04-15 21:13:48.

However according to Marko this revision is unlikely cause of this crash. But it could change access pattern such that it increased likelihood of this crash.

However according to Marko this revision is unlikely cause of this crash. But it could change access pattern such that it increased likelihood of this crash.
