IC98254: IDLE SAP CONNECTIONS NOT PURGED AS EXPECTED

IBM Integration Bus V9.0 - Fix Pack 9.0.0.2

APAR status

• Closed as program error.

Error description

• When connecting to SAP (or Siebel / PeopleSoft), you can
  configure a connectionIdleTimeout property in the configurable
  service. This is the number of seconds for which a connection
  can be idle before it is closed by IBM Integration Bus.
  
  A Java exception can occur in the processing associated with
  closing these connections, which results in idle connections not
  getting closed as expected. This exception (as reported in
  Service trace) is a java.util.ConcurrentModificationException.
  
  This can lead to connections continuing to accumulate, and
  eventually saturating the back-end server (for example the SAP
  R/3 server).
