    Description

      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.

              try {
                if (!journal.isFormatted()) {
                  LOG.warn("Journal cannot sync. Not formatted.");
                } else {
                  syncJournals();
                }
                Thread.sleep(journalSyncInterval);
              } catch (Throwable t) {
                 .......
