The separate thread for maintaining data source clients failed to complete
a comment given by the main thread. In most cases this is some kind of
configuration or temporary errors such as an attempt of non existent zone
or temporary DB connection failure. So the event is just logged and the
thread keeps running. In some rare cases, however, this may indicate
an internal bug and it may be better to restart the entire program.
So the log message should be carefully examined.
