Ran into something today that I can't seem to find much information on. I've got a single light forwarder instance that has stopped forwarding data. Checking metrics.log shows the following queueus are blocked:
I have several other identical forwarders that are not seeing these issues, and the indexer is showing no signs of strain. There aren't any connectivity issues between the forwarder and the indexer, nor any recent config changes. All the info I've found here regarding queue blockages at the indexer, so I get the impression this isn't a common issue.
Any ideas on what to look for here? I'm at a loss as to why this particular instance is failing.
