Description
Hello,
Edit: This may be related to MDEV-23851 but we would like to have confirmation from your side.
We upgraded MariaDB from 10.2.24 to 10.2.35 and the nodes in Cluster started crashing one day after the update. It seems to happen when there is a conflicting lock during a DELETE.
It's a 3-Nodes cluster. Every single node may crash a couple of times during a day. It also resulted in a crash of the whole cluster few times during the last two weeks.

It is possible that mysqld could use up to

key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 2329025 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.

Taking 29.12.2020 as example, when the monitoring system alarmed few times about node1 and node2 with the following message:
wsrep_cluster_status: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock'

It happened on node1 during December, 29th at:
- 08:40am
- 09:40am
- 03:50pm
Also on Dec, 29th on node2:
- 12:40am
- 12:50am
MariaDB crashed more times, though.

Attached the obfuscated logs from 29.12.2020 of all three nodes.
Is there any known workaround to avoid further crashes? I couldn't find any.
Many thanks in advance.
