>
> Currently, if there is an exception in _JournalNodeSyncer#syncJournal_, the
> sync daemon does not wait the specified interval before the next sync
> attempt.
> In the following code block in _JournalNodeSyncer#startSyncJournalsDaemon_,
> Thread.sleep should be moved to a separate try catch block from
> _syncJournal()_ to avoid skipping it in case of exception.
> {code}
> try {
> if (!journal.isFormatted()) {
> LOG.warn("Journal cannot sync. Not formatted.");
> } else {
> syncJournals();
> }
> Thread.sleep(journalSyncInterval);
> } catch (Throwable t) {
> .......
> {code}
