Research direction
Start by running tests.test_solver.Submission.test_cancel_batch repeatedly and observe its runtime, CPU, and memory behavior. Investigate whether prolonged execution or SAPI/QPU user throttling causes the resource spike. Done means identifying the cause and ensuring the test or client behavior prevents CPU and memory usage from reaching the reported levels.
Written by the indexing model from the issue text.
Description
Running the tests.test_solver.Submission.test_cancel_batch test, sometimes causes CPU and/or memory usage to increase to 100%/3-4GiB during prolonged test time of few minutes. Usually the test runs within 1m, but it has been observed to take 10m.
It is possible the reason for this is SAPI/QPU load, i.e. user throttling. Even if the reason is SAPI user throttling, the CPU/memory impact should be curbed.
