Major Description
Although MariaDB Galera Cluster does not support XA transactions but it still shouldn't crash server.
1. create a new db and a table
2. input a value
3. XA START 'test';
here where it crashed I received in the log
mariadbd: /home/jenkins/workspace/MariaDBE-Custom-bintar/label/rhel-7/wsrep-lib/src/transaction.cpp:123: int wsrep::transaction::start_transaction(const wsrep::transaction_id&): Assertion `active() == false' failed. |
201208 13:46:06 [ERROR] mysqld got signal 6 ; |
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: 10.4.15-9-MariaDB-enterprise-log |
key_buffer_size=134217728 |
read_buffer_size=131072 |
max_used_connections=6 |
max_threads=1002 |
thread_count=15 |
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 2336198 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...
