PROBLEM SUMMARY:
****************************************************************
* USERS AFFECTED: All users of z/VM TCPIP that secure *
* connections using the TLS/SSL server. *
****************************************************************
* PROBLEM DESCRIPTION: *
****************************************************************
* RECOMMENDATION: APPLY PTF *
****************************************************************
Through the process of securing connections, certain fields in
the key used for the TCP connection tree may be changed thus
invalidating the key. In this case, the tree node is deleted
and added back into the tree with the new key.
Some places that invalidated the key, failed to remove the
node from the TCP connection tree. In this case, when
consistency checking kicks off to check the tree, assertion
failures are flagged that are similar to this:

PROBLEM CONCLUSION:
Module T6PSSL has been updated to make sure all places that
invalidate the key for a TCP connection tree node, remove the
node from the tree and add it back in with the new key if
needed.
