rpcClient.Block(&block) return context.DeadlineErr

[ares0x]

When I execute with a single thread, I can get the correct block data, but when I execute the multithreading poll block, I will be prompted with contextDeadlineErr, how can I solve this problem?

client := rpc.NewRPCClient(node, types.ProdNetwork)
		log.Printf("val:%v",client.IsActive())
		result,err := client.Block(&height)
		if err != nil {
			log.Println(err)
		}
        log.Printf("result:%+v",result)

hi, How many threads do you create? And how many requests per second? The processability of node is limited, it will be stuck with a large number of requests, so contextDeadlineErr is expected in that situation.

Okay.Because of Biance-chain generates blocks quickly, I need to implement block data monitoring through multi-threading. My solution is this: If the local database stores 100 blocks behind the main network block, I open 60 goroutines to do the block polling. At this point, I will appear contex.DeadlinetErr。
