Defect/Fix: After a PVC detach occurred (which causes the stream to be closed), an
inbound request queued on the read side server was then running and passing the request
upwards on a now invalid stream. This resulted in the panic. The fix is to clear the read
size "q_ptr" field during the PVC detach processing which prevents any request pending on
the read side from being passed upwards.
• JAGab66302
Symptoms: This is an enhancement to zmasterd to accept .answ file on cold start.
Defect/Fix: zmasterd now accepts a .answ file on cold start and runs ttgen itself, as well as
being able to cold start from a .tmem file. This involves making changes in zmon such that
it can accept a .answ file for cold start, and run ttgen internally.
• JAGad00600
Symptoms: "zmasterd deact znode" does not kill the znode daemon.
Defect/Fix: "zmasterd deact znode" left znode still running, whereas "zmasterd deact
zmlog" removes zmlog from the run state.
The problem was occurring because the znode daemon was ignoring the SIGTERM signal.
Code has been modified so that the znode daemon no longer ignores the SIGTERM signal.
