If need some more information, just ask me that I'll try to provide. Thanks in advance.
Are you setting "AbortOnConnectFail" to false so it continues to try to reconnect? When a connection breaks (could be due to a failover etc), commands already sent to Redis on the now broken connection will timeout on the client.
