On the default ClickBench configuration of c6a.4xlarge (32 GB RAM).

This bug report is for the MariaDB team.

Sorry, what? Is it MariaDB bug or ClickBench bug? If it's MariaDB bug, it should've been in https://jira.mariadb.org, nobody will find it here. But it is in the ClickBench issues, so, I presume, it's a ClickBench issue, correct?

[alexey-milovidov]

@vuvova, that's MariaDB problem (not necessarily a bug, maybe it is not supposed to run on small machines).

Asking people to register on JIRA is a kind of offense.
At least you don't ask "jump on a quick call".

[vuvova]

Every bug tracker requires registration. One cannot report a ClickBench issue without registering on github either.

But if you don't want to register in Jira, you can report your issue on mariadb mailing list (I'm afraid it might require some kind of a confirmation for non-members) or on mariadb zulip (requires logging in to chat).

@vuvova I went to MariaDB - Joining the Community, then clicked the link in "If you have a feature request, you can file it in JIRA.", then got this:

Thanks! Someone put wrong links when editing the manual, it should be mariadb.com, but the link says mariadb.net. I've submitted a pull request to correct it

Let's fix MariaDB. No JIRA, no crashes.
