PM95911: EXCESSIVE CLOSE_WAITS ON CONTENT MANAGER

APAR status

• Closed as program error.

Error description

• Excessive Close_Waits on Content Manager.  The customer is
  seeing hundreds of these netstat CLOSE_WAIT port status states.
  Observed similar behavior in house Cognos 10.2.1 single server
  installation of only Content Manager service enabled. New socket
  connections get opened all the time from / to dynamic ports. In
  my environment, where socket wait time is set for seconds, the
  number of connections to / from the dispatcher port grows up to
  85-87 within minutes and then stays stable. There is also a
  number of connections in CLOSE_WAIT state.  Tested in 10.1.1
  environment. The number of connections grows and gets stable
  around 21-23. No connections in CLOSE_WAIT state.
