调研方向

Start with the reported System.Text.Json.Serialization.Tests.PipeTests_Async.VeryLargeJsonFileTest and StreamTests_Async.VeryLargeJsonFileTest failures in the build linked in the issue. The report identifies an OutOfMemoryException with payloadSize: 1000; investigate the failing test run and determine whether the failure is reproducible before proposing a fix. Done means the tests pass reliably without the memory failure.
