Just a heads-up... we're experiencing segfaults on the SBC.BlockExplorer.io block explorer pretty much at a 1 minute interval. Monit is restarting the Abe process lickety-split but I understand that it may be annoying to keep seeing an error page.
It appears to be an issue with API calls and I may have to disable all API access until we can get it sorted out. This will allow web visitors to use the system but you won't be able to use the API to power your coin tools. I don't think Abe was ever meant to directly serve over 1 request per second and it doesn't support a good caching strategy.
I'm going to put out a project proposal for someone to port Abe to a more performant framework/language (NodeJS, Golang, etc). The Abe codebase is a beast, so we'll focus on easily-maintainable code and, above all, generally error-free operation.
Again, sorry about the errors but we'll push ahead.
EDIT: Upgraded all PostgreSQL-related bits and the segfaults have appeared to stop. We'll keep monitoring it but we've re-enabled all API calls, in the mean time.
