MultiChain serious instability

Question

I am experimenting with MultiChain with Kutzman Kunstmaan Docker image.

And it is petty unstable. Each time dicker is restarted there was corrupted index problem so I had to add -reindex=1 to start scripts permanently.

Now I have other "interesting" corrupted data problems, like the recent one: ReadBlockFromDisk : Deserialize or I/O error - ReadCompactSize() : size too large

Is it only my setup (three different docker setups on three different machines) or you aware of such issues?

Answer 1

We're not aware of any chronic issues like this. What version of MultiChain is in the Kunstmann image? In general it is preferable to shut down MultiChain nodes properly (with the stop API command) rather that just perform a hard shutdown, although more recent versions recover from this situation much better.

Hi. Thank you for prompt answer.
We are using MultiChain Core Daemon build 1.0 alpha 21 protocol 10005 version.

We are hosting docker containers in cloud and we have limited control over shutdown process.
Do you have Linux script doing remote shutdown on node?

You just need to issue the command multichain-cli [chain-name] stop, so put that in your shutdown script assuming you have one?
