Qpid errors

Config file errors

If you see something like the following message in your system log when the qpidd service attempts to start:

Jul 22 15:39:08 localhost qpidd[8631]: 2013-07-22 15:39:08 [Broker] critical Unexpected error: Error in configuration file /etc/qpidd.conf: Bad argument: |cluster-mechanism=DIGEST-MD5 ANONYMOUS|

Replace 'cluster-mechanism' with 'ha-mechanism' in /etc/qpidd.conf then restart the qpidd service, or reboot.

sasldb errors

The qpid user database may become corrupted. This may be evidenced by error messages such as:

     qpidd: unable to open Berkeley db /var/lib/qpidd/qpidd.sasldb: No such file or directory

You can recreate the sasldb file using the following command:

     saslpasswd2 -f /var/lib/qpidd/qpidd.sasldb -u QPID guest

Provide the password at the command line (usually 'guest'), and the file will be created. You should further ensure that /etc/cinder/cinder.conf references the correct username and password corresponding with this file. Then restart qpidd:

     service qpidd restart

You can verify the presence of users accounts in that file with:

     sasldblistusers2 -f /var/lib/qpidd/qpidd.sasldb
