Description
All 3 nodes in Galera cluster crash as follows:
200219 12:29:11 [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: 10.3.18-*-MariaDB-*-log
|
key_buffer_size=134217728
|
read_buffer_size=131072
|
max_used_connections=82
|
max_threads=852
|
thread_count=90
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 2004324 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...

I could not repeat this with current 10.3 (10.3.24 commit b633b6a9d8278a3e0d9baaf83264fd007820c918)
CREATE TABLE t1(a int not null primary key) engine=InnoDB;

teemu.ollakka I assigned this to you as crash happens in wsrep-lib.
Do we have any progress on this? Any idea about the root cause?
