Windows server 2018 64bit running a java app using mariadb connector/J 2.5.4
Description
I am running MariaDB 10.4.12 on Windows Server 2018. I am connecting to it from a Java application using mariadb-java-client-2.5.4
I use Statement.executeQuery(string) to execute a query on the database. Most of the time this works without a problem, but I have just found that if the query is “DESCRIBE servers”, where servers is the name of a table, it crashes the MariaDB service.
I can run the query without a problem from the mysql shell, it is only when running it through the java connector.
The error log crash data is shown below.
Version: '10.4.12-MariaDB-log' socket: '' port: 3306 mariadb.org binary distribution
200624 15:48:11 [ERROR] mysqld got exception 0xc0000005 ;
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: 10.4.12-MariaDB-log
key_buffer_size=65536
read_buffer_size=131072
max_used_connections=16
max_threads=65537
thread_count=22
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 5380 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
