Abstract
Embodiments of the present disclosure provide a method, device and computer program product for managing an input/output (I/O) stack. The method comprises obtaining metadata related to an I/O request stored in the I/O stack, the metadata at least comprising a timestamp when the I/O request is placed in the I/O stack; determining, based on the timestamp, a length of time during which the I/O request waits for processing; and in response to the length of time exceeding a threshold time length, performing a predetermined operation on the I/O request to prevent the I/O stack from being congested.
