Question about "[ warn] [processor] failed to process chunk" messages output to terminal in debug logging mode.

[Tangosixteen]

Latest Fluentbit build, 5.1.0-1, but saw the same before upgrading from 3.2.2.

I see this quite a bit in debug output logs to the terminal:-

2026/08/13 21:44:25.153] [ warn] [processor] failed to process chunk

I've enabled the Dead Letter Queue stuff, and nothing ever gets written to the storage location, so there are no chunks to work with to troubleshoot the message. Could the message be spurious?

What next step could I take to see if something really is being dropped and we are missing important records in our cloudwatch?

Many thanks in advance to anyone who can point me in the right direction. Sorry for appearing dumb, if I could get chunk tracing outputting to the terminal that would be great, but not sure it's possible?
