This situation triggers when an OTMA TMEMBER is in a flood condition. A flood condition occurs when the percentage of TIBs (Transaction Instance Blocks) in use for a TMEMBER reaches 100%. Corrective action must be taken to relieve the flood condition as input is rejected for the TMEMBER until the condition is relieved. TIB growth can occur due to a stopped program, unavailable message region, message arrival rate exceeds processing rate, or failure to generate a CM1 IOPCB response leaving orphanned TIBs.
