APAR status
Closed as program error.
Error description
Additional Symptom(s) Search Keyword(s): A message flow running on Windows that calls the Integration API (IAPI) getConfigurableService() to access a "UserDefined" configurable service fails after 100 requests, even though the message flow calls disconnect() on the BroxyProxy object after each request. The default limit on concurrent local IAPI client connections is 100. The problem is that the Integration Node is not handling a broken named pipe correctly when the message flow disconnects such that the BrokerProxy object is not being successfully deregistered. The following error might be seen in a trace: BIP2112E: Integration node internal error: diagnostic information 'Could not launch a handler for a local CMP connection'
