Memory Usage Error with Typesense Cloud Service

HiHi!
We use Typesense cloud service as our search engine, 2 GB RAM & 2 vCPUs,
and now we had inserted many data into a specific collection.

But 1 hours ago, our monitor system shows this error message
[Errno 422] Rejecting write: running out of resource type: OUT_OF_MEMORY」
and cannot upsert our data into collection.

After checking threads.typesense post and the monitoring UI on typesense cloud,
we couldn't make sure that memory usage is above the threshold or not
(Like the image shows)

Can anyone help us to identify this question?
Thanks!

Total memory usage is swap usage + memory consumed which is exceeding 2 GB here.

Got it. Thanks for the answer.
I'll talk to my colleague and consider upgrading memory resource ~
