failed to load state at height error

[noot]

System info: [Include Ethermint commit, operating system name, and other relevant details]

Steps to reproduce:

1. I am trying to reproduce this on a 1-node network but so far have only been able to do it on a 3-node network.
2. start 3 node network as per fix consensus error #513
3. setup aragon truffle tests as per fix handler csdb usage, fixes consensus error again #516 then runtruffle test --network rpc
4. usually after a few of the suites have been run, you are no longer able to query for a block because of this error

$ geth attach http://172.17.0.2:8545

> eth.getBlock(1)
Error: invalid request: failed to load state at height 27985; version does not exist (latest height: 90086)

it seems to be caused by different tests, so I'm not sure exactly what is causing this to happen, or why it is trying to query for a state that is lower than the latest

what's your node pruning configuration? the ethermintd start should be used with the --pruning=nothing flag

[noot]

@fedekunze I'm not currently starting the nodes with that, I'll try that and see how it goes!

[fedekunze]

we should probably add some docs about pruning configurations

[noot]

@fedekunze setting --pruning=nothing fixed it :D closing this for now
