| # Wrapper script to allocate a port and fork a broker to listen on it. |
| # |
| # Instead of this: |
| # qpidd --port 0 <qpidd-args...> |
| # do this: |
| # qpidd-p0 <qpidd-args...> |
| # |
| # The port is bound by python code, and then handed over to the broker via the |
| # --socket-fd option. This avoids problems with the qpidd --port 0 option which |
| # ocassional fails with an "address in use" error. It's not clear why --port 0 |
| # doesn't work, it may be to do with the way qpidd binds a port to multiple |
| # addresses on a multi-homed host. |
