logrep ommiting lines when no filter applied

[mikerj1]

Hello - I have an access log that contains ~42mil entries. Using the command logrep -o cc,ip,ts,year,month,day,hour,minute,method,url,status,ref,refdom,ua access.log_all > access_logs_prepped, I intended to create a file containing all entries, but formated witht the logrep output.

The file access_logs_prepped contains 1,126 fewer lines than access.log_all. Since I didn't apply a filter, I would expect the line count to be the same. Does logrep contain options that can help account for this discrepency?

Is it possible that the access log contains invalid entries (ex. incomplete lines introduced during log rotation)?

Have you tried invoking it with -d and piping stdout to /dev/null to see if there are any helpful errors?
