This avoids hitting the hard wall for connections with non-compliant
peers that are accumulating errors. We recycle the connection early
enough to permit to reset the counter. Example below with a threshold
set to 100:
Before, 1% errors:

# time conns tot_conn tot_req tot_bytes err cps rps bps ttfb
