Updates CAF to fix an issue in Broker where the pipeline could stall, completely blocking communication eventually. Relates zeek/zeek#2389. Also includes a patch that backports the
process_open_fds
Prometheus metric (very useful to double-check whether the peerings recorded by Broker are actually accurate).Unfortunately, this isn't the end of the story. In my test setup, I sometimes get Broker into a state where peers would constantly disconnect and then reconnect. This would match the "flurry of activity in cluster.log" that Christian's reported. That bug is most likely on the Broker side and I'm already looking into it.
