@clabby My changes have captured the lines that you have shared in image attached to the issue.

Just wanted to check whether we wanted to handle the general case of ::Temporary(_) with a trace log:

kona/crates/derive/src/pipeline/core.rs

Line 108 in 24e73ba

if let PipelineErrorKind::Temporary(PipelineError::Eof) = err {

And whether we want to consider any other temporary errors here:

kona/crates/derive/src/stages/batch/batch_queue.rs

Line 356 in 24e73ba

if let PipelineErrorKind::Temporary(PipelineError::Eof) = e {

and

kona/crates/derive/src/stages/channel/channel_bank.rs

Line 201 in 24e73ba

if !matches!(e, PipelineErrorKind::Temporary(PipelineError::Eof)) {
