Promtail windows client missing log lines

as of promtail for Windows 2.3.0, we are missing log lines in Loki.

was originally

2021-11-10_08h49_50

So we got only one line at …, 255, but …, 214 has all two lines. There has been no end of file inbetween. This is not a query issue either, I tried different |= expressions (“2021-11-10 10:01:18” and “read-7194”).

Were there any related changes after 2.3.0? Is there anything else I can check?

Thank you!

updated to 2.4.1, same behavior.

found “entry out of order” logs in Loki log file, updated Loki to 2.4.1 - no dropped entries so far.
