After configuring or modifying an Oracle Database Gateway listener such as DG4MSQL or DG4ODBC, attempts to start the listener hang.

The following message is displayed in the listener log -

<msg time='2015-09-16T12:17:36.903-04:00' org_id='oracle' comp_id='tnslsnr'
type='UNKNOWN' level='16' host_id='some ID'
<txt>Dynamic address is already listened on (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=hostname)(PORT=1521)))



 The listener was previously configured and working but was then modified to add additional SIDs or to change the listener port.
