 % AUTH_DATASRC_CLIENTS_BUILDER_FAILED data source builder thread stopped due to an exception: %1
 The separate thread for maintaining data source clients has been

-catch this condition in timely fashion, and there is no way to recover
-from this situation except for restarting the entire server.  So this

+cannot always catch this condition in a timely fashion and it would be
+worse to keep running with such a half-broken state.  This is really
+an unexpected event and should generally indicate an internal bug.
+It's advisable to file a bug report when this message is logged (and

 % AUTH_DATASRC_CLIENTS_BUILDER_FAILED_UNEXPECTED data source builder thread stopped due to an unexpected exception
 This is similar to AUTH_DATASRC_CLIENTS_BUILDER_FAILED, but the

-to be restarted by hand.
