Error description
CDSA suspend queue processing appears to stall when there are over 1000 suspended sessions.
Local fix
Problem summary
Users Affected: All Problem Description: In burst scenarios where 1000s of BPs are attempting (at virtually the same time) to transmit a file from a CDSA (PNODE) to a remote node (SNODE) which is severely restricted to less than 5 concurrent sesssions, suspend queue processing appears to "stall" becuase of the pace at which the queued entries are resumed. Platforms Affected: Unix/Linux Windows iSeries
Problem conclusion
Resolution Summary: A code fix is provided. Depending on session limit restrictions, burst scenarios can significantly increase the SHSL suspend queue depth. Prior to the fix, the deeper the queue became, the slower its processing became. After the fix, queue depth has virtually no impact on queue processing; performance is significantly improved, especially in burst scenarios. Delivered In: 5020500_18 5020601_10 5020602_6 5020603_6
