Stopped Syncing #5,503,550

[MysticRyuujin]

My node has stopped syning for almost 10 days now, and I've tried clearing caches, restarting, updating, etc.

I stopped the process, cleared the logs, cleared the cache, pulled the latest from git, started it, let it run a little while, collected the logs. Here they are:

harmonylogs.zip

The only error I see is here:

[mkalinin]

to get a full understanding of what has happened I am wonder whether you did change database.prune.maxDepth in the config or not?

[MysticRyuujin]

@mkalinin - no I haven't changed ANY settings other than manually adding 2 custom peers.

[mkalinin]

@MysticRyuujin would it be a problem for you to upload database folder to some resource? I made a fix and would like to test it with your data sample

[mkalinin]

This should be fixed by https://github.com/ethereum/ethereumj/commit/99e22a557a7f88cc308f7931548cefefcaabb9cc @MysticRyuujin thanks a lot for assistance!
