Hi We're running into a situation where Heka reports about "idle packs" and is "wedged". See the Heka diagnostics in <https://gist.github.com/elemoine/f533f674c514406fb6a320bd034d2568>.
So the inject and input recycle channels are empty – no free packs. And the http_metrics_filter sandbox is blocked in an inject_message() call waiting for a free inject pack. We read other threads [*] discussing similar issues, but our case may be a bit different. The http_metrics_fliter gets messages from logstreamer inputs, and it injects messages that will be consumed by the influxdb_accumulator_filter. I think our case is different because the upstream filter (http_metrics_fliter), as opposed to the downstream filter (influxdb_accumulator_filter), is blocked. How can this be possible? And I really wonder where the inject packs are! The inject recycle channel is empty, so who holds the inject packs? There are 30 idle inject packs attributed to the influxdb_accumulator_filter, although that filter's match channel length is 0 (so is its input channel length). So I do not understand how this sandbox filter can have idle packs! And where are the remaining 70 inject packs? Any idea? In case this is relevant: we use buffering for the output plugins (with full_action drop), and no buffering for the filters. This is blocking us big time. Any insight is welcome. Thanks!
