Initialization stops at block 1898

To initialize my database I use myth -i --init-db. It’s been slow and riddled with 502 errors along the way, but restarting each time has gotten things going. Now it’s stuck on Resuming synchronization from block 1898 and doesn’t seem to move forward no matter how long I wait. I ran a git pull to make sure I was using the latest version of the project and I’m running it in a Docker instance.

Any suggestions to make it finish up so I can get to the point where I sync the difference between the head block at the time I started this and now? Alternatively, I’m willing to forego the first 1898 ETH blocks in existence and just sync the latest into the database. Is there a way to do that?

Edit: It appears there’s an intermittent error involved in processing this block:

The above exception was the direct cause of the following exception:

This worked to reset back to syncing from the top, thanks again guys!

FYI, here is my proposal for refactoring the search feature. This would require users to run a local node to use the search, but I think it’s the best way to make sure the feature is useful and returns accurate results. Feedback is appreciated!
