Description
A user saw the following crash with semisynchronous replication in MariaDB 10.3.13:
2019-04-26 15:57:38 778 [Note] Start binlog_dump to slave_server(54823151), pos(mariadb-2-bin.000001, 24898028)
|
2019-04-26 15:57:38 778 [Note] Semi-sync replication switched ON with slave (server_id: 54823151) at (mariadb-2-bin.000001, 4)

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: 10.3.13-MariaDB-log
|
key_buffer_size=134217728
|
read_buffer_size=131072
|
max_used_connections=5
|
max_threads=153
|
thread_count=65
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467390 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...
