SUMMARY:
When starting the Progress SonicMQ Version 3.x Broker, it may issue the following error:
[146] progress.message.broker.EStartupFailure: Broker already running
EXPLANATION:
This error can occur in the following scenarios:
-- The port specified in the broker.ini conflicts with one already
used by other programs.
-- The SonicMQ Broker has been started more than once using the
same port.
SOLUTION:
1) Make sure the port specified within the broker.ini file with the
parameter PORT or PORT_NUMBER_n, is not used by other programs.
The "netstat" command can be issued to check if a specific port is
in use. (See Progress Knowledge Base Solution 20559).
NOTE: The use of port 80 is not recommended, especially if a
Web Server is running on the same machine as SonicMQ.
This is because most Web Servers use port 80 as a default port.
2) Make sure the Broker was not started more than once on the
same machine using the same port number defined in the same
broker.ini file.
