It appears that my node forked on height 8974060 with output message below:

And restart didn't solve the problem, still with error:

[ChrisRut]

Is there a way to recover from this situation (without patching or running master), or do we need to wait until 1.1.5 is released?

[ghost]

@ChrisRut There are 3 ways I have tried: 1.Restart, maybe OK. 2.Restart with --replay-blockchain or --hard-replay-blockchain.Sometimes needs to replay, but to replay may takes several hours. if to hardreplay, it needs more time. 3.Using the latest backup data,this is the best way sometimes.

[sivachaitanya]

@spartucus How did you resolve this ?

[spartucus]

@sivachaitanya I updated to the last version.

[rameshb444]

Is this issue resolved?

I am using v1.4.1, I am getting the same error.

@rameshb444 This happens on its own and all you can do is either rectify on its own or restart the network or update to latest client version
