> A seg fault occurs in the client library when reopening a connection after
> reports of lack of available file handles looking something like:
> #0 qpid::client::TCPConnector::closeInternal (this=0x9d1b140)
> at qpid/client/Connector.cpp:227
> 227 aio->queueForDeletion();
> (gdb) bt
> #0 qpid::client::TCPConnector::closeInternal (this=0x9d1b140)
> at qpid/client/Connector.cpp:227
> #1 0x00a6dc3d in qpid::client::TCPConnector::close (this=0x9d1b140)
> at qpid/client/Connector.cpp:240
> #2 0x00a627e4 in ~ConnectionImpl (this=0x9d1abe0)
> at qpid/client/ConnectionImpl.cpp:92
> #3 0x00a56fc8 in boost::detail::sp_counted_impl_p<qpid::client::ConnectionImpl>::dispose (this=0x9d1b058) at /usr/include/boost/checked_delete.hpp:34
> #4 0x00a5590e in qpid::client::Connection::open (this=0xbfb3ec64,
> settings=@0xbfb3ec24)
> 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.
