From: "Lee A. Roberts" <redacted> Resolve SCTP association hangs observed during SCTP stress testing. Observable symptoms include communications hangs with data being held in the association reassembly and/or lobby (ordering) queues. Close examination of reassembly queue shows missing packets. In sctp_ulpq_renege_list(), events being reneged from the ordering queue may correspond to multiple TSNs. Identify all affected packets; sum freed space and renege from the tsnmap.
