CentOS 8.2, 3 Node Galera Cluster
Description
We are attempting to deploy Galera on a large high I/O environment, and the cluster continues to loose state due to failing MariaDB servers. The server continues to segfault trying to roll forward transactions. It eventually comes up, but then other servers are expelled from the cluster. We are running from the MariaDB.repo on MariaDB-Server-10.5.8-1
The backtrace looks like the following:
201211 8:50:43 [ERROR] mysqld got signal 11 ;
|
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: 10.5.8-MariaDB-log
|
key_buffer_size=134217728
|
read_buffer_size=131072
|
max_used_connections=0
|
max_threads=1502
|
thread_count=10
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 307971051 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...
