 Description   

We have a single Server and try to load data into Maria-DB Columnstore while performing some queries via Pentaho.

After a few Minutes we get the following error in the MariaDB-Error-Log... Please find attached the ColumnstoreSuppport-Report.

Did we something terribly wrong with Buffers?! Thank you in advance for your help.

Maria-DB Error Log:

210223 15:48:14 [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
key_buffer_size=134217728
read_buffer_size=4194304
max_used_connections=11
max_threads=153
thread_count=12
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 642490132 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...
