APAR status

  • Closed as program error.

Error description

  • After some communication error occurs an mq front side handler
may stop polling or reading from the queue. The mq-qm status
will show no active connections:
<TotalActiveConn>0</TotalActive
Conn>
<ActiveFrontConn>0</ActiveFrontConn>

The administrative
state of the mq-qm object and the front side handler are
enabled and showing as UP but simply have no connections.

Local fix

  • A quick fix would be to increase the concurrent connections by
1 on the MQ front side handler and apply the change. This will
force a connection pool change and allow the FSH to resume
reading from the queue.

Problem summary

  • MQ stop processing when using MQ with SSL.

Problem conclusion

  • Fix is available in 2018.4.1.17 and 10.0.1.4.

Temporary fix
