There seems to be a memory leak somewhere in #ONI.

Doing a load test on a test instance for about 5m leads to memory increasing from the nominal ~100Mb to over the maximum of 250Mb and getting reaped by the OOM.

The load wasn't very high, about 5 concurrent requests.

Screenshot from a cloud dashboard showing the Graph for memory usage of an ONI instance before, during, and after two short load tests.

The timeline spans from 11:20AM to 12:16PM.

The nominal value for memory seems to be around 97-100MB.

At 11:52AM there's a double spike growing fast to the maximum of 250MB happening around 11:56AM. At that point the instance is replaced by another one that follows the same pattern with two sharp peaks at 250MB which also gets replaced around 12:01PM.

If you have a fediverse account, you can quote this note from your own instance. Search https://metalhead.club/users/mariusor/statuses/115734659540196571 on your instance and quote it. (Note that quoting is not supported in Mastodon.)
