Your server ran out of RAM
2024-08-26T13:25:31.123811Z 1172186 [ERROR] [MY-010934] [Server] Out of memory (Needed 75888 bytes)

check your config to see if mysql is requesting more memory than you have.

Thank you for your interest in MySQL.

Hi.

Thanks for your answer.

I realise this is no place to ask for help, that's why I didn't. I'm aware MySQL-server reported "Out of memory", but the logs also show that it consumed about 14GB out of 24GB at that time. That's why I chose to let you know about the issue, and figure out for your self, if this was a bug you needed to look into.

Feel free to delete the report. Thanks.
