Fluent-Bit 1.8.13 : Problem with duplicated record

[googleg]

Hi all,
Sorry I am new to this group and I hope I am posting this in the right place.

I've been using td-agent-bit for a year on a Raspberry pi4 to ship alert logs from Suricata to a local Elasticsearch instance, using the tail plugin. It's been working just fine with absolutely 0 issue but after upgrading from 1.8.12 to 1.8.13, I started getting duplicated records (sometimes 10-20 times the same record) in ES.

I tried to troubleshoot the issue and quickly came to the conclusion that td-agent-bit was the culprit. In last resort, I ended up downgrading the package from 1.8.13 back to 1.8.12, and after that the issue just disappeared and things came back to normal. Unfortunately, I am not too sure what to do to troubleshoot more precisely.

Was this reported before ? Is this a known problem with 1.8.13 ? Or is it something specific to the armhf package ?
