Solutions

1. Wait for the running memory-agent action to finish before starting another one.
2. Cancel the in-progress action if it is stuck, then retry.

Example fix

Let the current 'Calculate retained size' (or similar) action complete, then run the next memory analysis action.

When it happens

Trigger: A memory agent operation is requested while a previous one is still executing.

Common situations: Repeatedly triggering memory analysis (e.g. object size calculation) in the debugger before the previous run finished.
