APAR status

• Closed as program error.

Error description

• When a number of FSHs are opened against a single backend server
  object, for example JMS connections, the customer might see only
  some are in up state and others are down.  This is more
  prevalent on virtual appliances with limited RAM.
  

Local fix

• Distribute the number of FSH handles to multiple server
  connections.
  

Problem summary

• Customers with many JMS Front Side Handlers [FSHs] bound to one
  JMS server/connection object might experience problems where not
  all the FSHs start properly and sustain an Operational State UP.
  This can be especially visible on virtual platforms with limited
  RAM.
  

Problem conclusion

• Fix is available in 6.0.0.14, 6.0.1.10, 7.0.0.7 and 7.1.0.5.

Temporary fix

• Create more JMS Server objects (with possibly the same settings
  as the original one) and distribute the JMS FSHs evenly across
  all of them.
