Running a find command with maxTimeMS that creates a tailable, non-awaitData cursor will set a limit on the server-side execution time for future getMore requests. This gist shows a series of find and getMore commands to reproduce the issue: https://gist.github.com/kevinAlbs/34e377d226a0394d016de436bfe829ef. The initial find command is run against a non-empty capped collection. Note that this is probably also an issue for aggregate.
