Systems methods and computer products for reclaiming resident buffers on demand. Exemplary embodiments include systems and methods for reclaiming resident buffers, including allocating a buffer, determining that the buffer allocation pushes the buffer pool below a reclaim threshold, marking an oldest in-use buffer to be reclaimed, determining that all messages referencing the buffer have been queued, allocating a new buffer and performing a swap of the oldest in-use buffer and the new buffer, performing a free message block operation and updating a message block by updating a set of read and write pointers to point to the new buffer.

Reclaiming resident buffers when a reclaim threshold has been exceeded by swapping the oldest in use buffer and a new buffer, and referencing the new buffer via an updated set of read and write pointers
