Sometimes it can reproduced with
mysqlslap --user=maxscale --password=xxxxx --host=127.0.0.1 --port=4006 --concurrency=50 --iterations=1000 --create-schema=test --query="commit;insert into test.t1 (a) values('test');select * from test.t1 limit 2;begin;insert into test.t1 (a) values('test');commit;begin;" |
Works fine with Maxscale 2.2
