9.1.1.5: PTF UI44156 for Rational Developer for System z

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• In RDz v9.1, the sockets with which RSED communicates with the
  JMON server may be
  not closed properly by the client side and left in a close_wait
  state. This happens if JMON
  has closed the connection after a timeout due to inactivity.
  
  The socket is closed when RSE tries to use it again and notices
  the connection is gone.
  

Local fix

• None. However, the sockets in the close_wait do not have any
  observed side effects, and can be normally ignored.
