be expected. I.e., the client just kills the stream at some point for whatever reason.

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Fragmented TCP packets will still be directed to the ‘wrong’ RSS queue, but will ultimately be copied to the correct worker thread. They may arrive out-of-order,
not sure how much of an issue this is. Something you could do to further test this would be to enable full file logging/extraction and look for files tagged as “TRUNCATED” in the eve logs. That’s a ‘red flag’ that the stream tracking isn’t working properly
for big TCP flows. Keep in mind you will always see some truncated files organically; however if you see the same file being truncated that’s indicative of a problem with TCP flow tracking for that particular network.
