Red Hat Enterprise Linux release 8.10 (Ootpa)

Intel(R) Xeon(R) CPU E5-2697 v3 @ 2.60GHz
Description
Using spider we have 2 nodes that both connect to 3 backend servers
Post 10.11.10 upgrade from 10.6 using this adhoc query I can near instantly crash the server with this query
# eventdata

SELECT ms.name AS microservice_name, ot.name AS object_type_name, ed.object_id AS account_or_user_id, edk.name as key_name, ed.happened_at, ed.value |
FROM event_data AS ed |
JOIN event_data_key AS edk ON edk.event_data_key_id = ed.event_data_key_id |
JOIN microservice AS ms ON ms.microservice_id = edk.microservice_id |
JOIN object_type AS ot ON ot.object_type_id = edk.object_type_id |
WHERE ed.object_id IN (1118579) |
AND ed.happened_at BETWEEN '2025-07-01' AND NOW() |
ORDER BY ed.happened_at ASC |
LIMIT 5000;

SELECT edk.name, ed.happened_at, ed.value |

AND IF(NULL IS NULL, 1=1, edk.name = NULL) |
ORDER BY ed.happened_at ASC |
LIMIT 5000;

From a SP we run regularly this completes fine, additional parameters in where
SELECT edk.name, ed.happened_at, ed.value |
FROM event_data AS ed |
JOIN event_data_key AS edk ON edk.event_data_key_id = ed.event_data_key_id |
JOIN microservice AS ms ON ms.microservice_id = edk.microservice_id |
JOIN object_type AS ot ON ot.object_type_id = edk.object_type_id |
WHERE ms.name = 'clientapi' |
AND ot.name = 'account' |
AND ed.object_id = 1118579 |
AND ed.happened_at BETWEEN '2025-07-01' AND NOW() |
AND IF(NULL IS NULL, 1=1, edk.name = NULL) |
ORDER BY ed.happened_at ASC |
LIMIT 5000;

250912 11:56:27 [ERROR] mysqld got signal 11 ;
|
Sorry, we probably made a mistake, and this is a bug.
|
|
|
Your assistance in bug reporting will enable us to fix this for the next release.
|
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.
|
|

|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 17757450 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...
