Geth version: Geth/v1.8.4-stable-2423ae01/linux-amd64/go1.10
OS & Version: Ubuntu 16.04

Ever since I updated from v1.8.2 to v1.8.4 my Geth node has struggled to maintain sync.

It will run for a while then it just seems to stop syncing. Below is the error I see right before it stops syncing

I used geth version 1.7.3, my node was working fine until yesterday - 20/04, I got the same issue with you. Besides almost all rpc methods call to my node take too long time to response. Especial, time response of estimateGas always up to 60s. I tried to upgrade geth to version 1.8.3 but nothing better.
But today, everything is getting better. I don't know what happened, I didn't do anything.

I suspect this is a duplicate of #16539 , and Transaction stats report failed is unrelated.
