Created attachment 344778 [details] reproducer Description of problem: A seg fault occurs in the client library when reopening a connection after reports of lack of available file handles. Version-Release number of selected component (if applicable): qpidd-0.5.752581-5.el5 How reproducible: 100% with attached reproducer Steps to Reproduce: 1. start broker 2. run attached test case Actual results: core dump Expected results: no core dump Additional info: If when opening a connection there is only one file handle remaining, the socket for the connection is created, but the fds required for the poller's readable pipe are not available. Initialisation of the connectors Poller object fails and the AsynchIO object is left uninitialised. However the closed flag has already been set to false so when the associated connector is then deleted (e.g. on reopening the connection), it tries to shutdown the AsynchIO object which has not been initialised and there is a segfault.
