Something strange is going on with the RSS feed parsing system. I'm not sure what, but it appears that it is falling behind.
I think it might be a priority inversion in the webspider queue management system, but I haven't nailed it down completely, yet. Anyways, updates may be spotty for a few days until I figure out what caused what.
I've resolved the issue with broken updater. I had to re-provision the private SSL certificates used for the RabbitMQ broker communications.
Anyways, the RabbitMQ host server is now on Ubuntu 16.04 LTS, so it shouldn't need much for another few years other then regular updates as well.
Basically, I rebooted the rabbitmq server that manages the update communications from the web-spider backend, and rabbitmq didn't come back. It turns out that there are unhandled version incompatibilities between the latest version of erlang and the latest version of rabbitmq that is packaged by the rabbitmq devs for ubuntu 14.04.
Anyways, I'm in the process of updating the rabbitmq server, but distribution updates are always kind of dangerous, particularly when (as in this case) you use a lot of non-standard apt-get repositories. We'll see what happens.
The database versioning table has been migrated to a 4 TB partition, which should mean it has plenty of space to grow for the next few years.
I'm migrating database backing volumes. The feed feeder database is down at the moment, and it'll probably take several more hours for the copy to complete.
