… - b28 On server side, when IO handler repeatedly hit -DER_TX_RESTART, then it is quite possible that the -DER_TX_RESTART failure is related with server overload or some congestion caused RPC delay. Under such case, server retry with newer epoch may increase server workload/congestion. Then let's ask client to retry with some backoff delay. Signed-off-by: Fan Yong <fan.yong@hpe.com>
