IT31767: SOCKET HANDLE LEAK IN BIPBROKER WHEN MAXLOCALIAPICLIENTS LIMIT REACHED

APAR status

• Closed as program error.

Error description

• The bipbroker process (Admin Agent) can handle 100 (default)
  locally connected Integration API (IAPI) clients at the same
  time. This limit can be configured by changing the value of the
  maxLocalIAPIClients property of the agent's DeployThreadManager
  object using the mqsichangeproperties command. If the maximum
  number of local IAPI client connections has been reached, and a
  new connection request is received, the bipbroker process
  rejects the request and a BIP2112 ''Could not launch a handler
  for a local CMP connection" error is logged to the system log.
  But whenever this occurs, a socket file handle is leaked and
  the process may eventually be unable to allocate new file
  handles.
  

Local fix

• NA
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of IBM Integration Bus V10 using local Integration API
  client connections.
  
  
  Platforms affected:
  z/OS, MultiPlatform

  PROBLEM DESCRIPTION:
  The bipbroker process (Admin Agent) can handle 100 (default)
  locally connected Integration API (IAPI) clients at the same
  time. This limit can be configured by changing the value of the
  maxLocalIAPIClients property of the agent's DeployThreadManager
  object using the mqsichangeproperties command. If the maximum
  number of local IAPI client connections has been reached, and a
  new connection request is received, the bipbroker process
  rejects the request and the following error is written to the
  syslog:
  
  BIP2112E: Integration node internal error: diagnostic
  information ''Could not launch a handler for a local CMP
  connection''
  
  But whenever this occurs, a socket file handle is leaked and the
  process may eventually be unable to allocate new file
  handles.
  

Problem conclusion

• The product no longer leaks a socket handle when a new thread
  cannot be started to handle the local IAPI client connection
  request.
