Log Message:
- Error handling for "ERROR: could not serialize access due to
  concurrent update"

If this error is encountered when starting processing of
sl_archive_counter, then two threads are fighting over access to this
counter, and at least one has just failed.

Rather than waiting, we ask to restart the node immediately.
