Since we are using MariaDB 10.4.8 we've been getting several issues. We have a cluster of 3 nodes with Galera. In the last week, we've got some crashes everyday. Yesterday, we experienced a crash every 5 mins that usually meant two severs down.
For this reason, we upgraded to 10.4.10 to see if this version patched anything related to our crashes. However, we again were in the same escenario.
Finally, we had to perform a rollback to an older version: 10.2.29. And since yesterday we do not have any crashes.
I'm attaching logs from 10.4.8 and 10.4.10 that were continuously crashing. Everytime same traces. We cannot reproduce this again as we are in production and need stability, so we are not in that version again, a bit worried to upgrade again in a near future.
Some key lines in the logs:
Do you need any more information?
