Caught Exception from bitcoind: EOF occurred in violation of protocol

getting this a lot after starting a fresh instance of blockstored:

@peacekeeper This can happen when there is intermittent network jitter, or if the bitcoind fleet we're running in AWS is under particularly high load. It shouldn't affect the correctness of the system--Blockstore simply retries whatever RPC it issued whenever it encounters a network-level error such as this.

What I can do is have Blockstore avoid logging recoverable errors such as this.

[peacekeeper]

Thanks for the explanation, good to know this doesn't break anything. Interestingly I believe I also saw the same errors when setting "use_https = False", but I can't confirm that right now, would have to check again.

I saw this same/simliar error on both Bitseed and my intel machine when i built blockstore for them last night. I am using a local bitcoind txindex=1 in both cases. Blockstored was able to talk my local bitcoind in the past.

The error repeats infinitely

upon running blockstored start:

....repeats forever....

@peacekeeper @jfeldis When you get a chance, please post your ~/.blockstore/blockstore.ini files (with your secrets omitted), so I can try to reproduce the problem on my machine. Thanks!

Should be fixed now; reopen if not.
