I upgraded to v0.4.27.2 from v0.4.27.1. The Qt client wasn't synchronizing the blockchain properly so I used the CLI client. The CLI client did download and index the blockchain up to the present. I then switched over to the Qt client and it appeared to be synchronized to the present and working fine for a moment. But then I realized that it wasn't updating the blockchain and just started getting further and further behind from the present.
I switched back to the v0.4.27.1 Qt client (which had its bugs
but at least synchronized the blockchain) and surprisingly it too had the same blockchain synchronizing problems as the v0.4.27.2 Qt client.
I then tried deleting the chain directory and downloading the blockchain from scratch using the v0.4.27.2 CLI client (which took a long time by the way). I then loaded the v0.4.27.2 Qt client on this new chain folder and the same problem of it not updating the blockchain and falling behind persisted. However, this time when I switched back to the v0.4.27.1 Qt client, the client went back to properly synchronizing the blockchain again as it did before the "upgrade". So, I'm just sticking with v0.4.27.1 for now (despite the annoying lags described previously
) because at least it functions.
I am not sure what other information I can provide to help track this bug down. Has anyone else experienced this problem?
