With all of my recent ftPerl love, I’ve found that the quickest way to at least start troubleshooting it is to reconfigure the offending host for HA. This is fine if working in a small environment, or on a small number of hosts, but there are a metric ton of these hosts gone sideways all [...]

Nodes send a heartbeat to [...]
